New PV cell coating increases Efficiency and Durability

27 March

Solar Power Management Pdf.pdf

An innovative new coating technology from MetaShield can make photovoltaic (PV) cell surfaces more durable while it increases efficiency more than 1 percent, all without significant changes in cell or module production processes. By Mark Andrews, Technical Editor.

IMAGINE working years to develop a product to enhance photovoltaic (PV) efficiency, and then at a critical juncture – after more than 40 trials – a test batch falls to the floor, shattering into pieces. The average researcher would have been doubledover at the loss. But for MetaShield founder and CEO Martin Ben-Dayan, the lab accident proved to be just the sort of break he had been looking to find.

When everything crashed it seemed the incident was just another frustration in the life of a new business. Anyone who has built a company or worked at a startup can attest that setbacks often outnumber ‘eureka!’ moments. But as researchers and Ben-Dayan were literally picking up the pieces, they discovered something unexpected. Instead of shattering every test slide, the fall left some intact.

But only slides coated with their 43rd formulation had survived. Every other slide was cracked if not smashed. MetaShield would eventually determine that their breakthrough formula was capable of increasing the break resistance of glass up to four times.

“Up until then, we had been working with polymers; we subsequently transferred over to a silica-based approach,” said Ben-Dayan. “When the tray fell some slides broke and others didn’t. We found only one group survived and we realized at that point we had something on our hands that was potentially much bigger than we had planned. The coating was super-light and thin and could host nanoparticles. When dried it was super-tough; it made things like glass (or PV cells) much stronger.”

Once durability was established, MetaShield moved on to its primary goal: create a coating to improve PV performance. Enhancing nanoparticles were added to the base formula and more tests were conducted.

“Durability is great, but could (the coating) enhance efficiency? We found that it could. So now we had a new formulation that could be sprayed on a solar cell; it dried at room temperature without any special treatment. We (also) found it could go on top of the antireflective coatings that PV manufacturers were already using. It increased efficiency one percent or more. That is significant in the solar industry.”

Polymers, and to a lesser extent silica coatings, are of course not new in 21st century industry. According to Ben-Dayan, employing nanotechnology made the difference. As MetaShield also discovered, their nanoparticle formula simplified production compared to typical silica or polymer coatings.

“By now we started to realize that we were part of something very new. If you have a material with all of the benefits of polymers but has the properties of glass, then it is disruptive, even revolutionary. With (traditional) silica coatings you have to use very expensive deposition and baking processes.
As we spoke to more people in the industry, we realized that while the break resistance and efficiency (gains) in our formulas were impressive, what most people were interested in was the fact it could be applied and dried at room temperature. That made a real difference,” he remarked. Ben-Dayan said his company’s quest to enhance PV cell efficiency started six years ago. With offices in New York and Utah, the company had originally pursued optical filters to boost solar cell efficiency. They struck on the idea of using holographic optical elements to change the direction of light to strike the active areas more effectively, thereby boosting the yield of PV cells.

“That product worked, but the value metrics for us and the economics were not beneficial. So after a year or so, we transitioned into nanotechnology to help manipulate what was going on as the light waves entered through the filter (layer). We had tried quite a few formulations with various nanoparticles, but in the process we discovered it did so much more.”

Now armed with a product that could appeal to many industries, Ben-Dayan set out to market his technology. Since the product increased durability and efficiency, MetaShield representatives spoke with aerospace companies developing satellites for defense and commercial applications that rely on high-performance, triple junction PV technology for electrical power in space.

The company also received a grant from the Utah Science Technology and Research Initiative (USTAR) to prove the potential of its new coatings and thereby establish greater credibility with potential customers. That study was conducted at MetaShield R&D facilities in Utah with results verified late in 2016 by OAI-Optical Associates, a leading testing company in San Jose, California.

Tests found that MetaShieldPV, when applied to triple junction solar cells, boosted their efficiency 1.2 percent (absolute). This increase amounts to what industry watchers like GTM Research expects from five years of conventional PV cell technology evolution as manufacturers pursue product improvements over time; about 0.2 percent each year is average.

The initial study focused on triple junction GaInP/ GaInAs/Ge solar cells. These devices were coated with MetaShieldPV; before they were not encapsulated; they had already received commercial antireflective (AR) coatings. The current-voltage measurements (J-V curve) of the devices were measured under AM1.5 simulated solar spectrum illumination at OAI-Optical Associates, before and after the coating was applied. The comparison revealed an increase in device efficiency from 29.39 percent to 30.59 percent, an absolute increase of 1.2 percent.

While test results with more conventional c-Si cells coated in MetaShieldPV are still pending, Ben-Dayan said he expects the company’s own performance reviews to be verified by OAI-Optical Associates. The precise formulation of MetaShield base coating products is proprietary, but Ben-Dayan said the base is primarily silica, water and ethyl alcohol. The nanoparticle formulation is also proprietary. Upon application, the product solidifies in the open air at room temperature without any special industrial gases, heating or pressurization. The liquid hardens into a thin film layer with a refractive index of ~1.5, according to the company.

The MetaShieldPV coating employs plasmonic and dielectric nanoparticles to enhance the forward scattering of light incident on solar cells and through this process increases the short circuit current and the overall photo-conversion efficiency of PV cells, explained Glenn Mesa, MetaShield’s director of research and development.

Once the core of its lineup was fashioned, Ben-Dayan and his team went to industry events and conferences, this time to introduce their new products. They leveraged early aerospace contacts, expanding outreach to defense contractors. They have also engaged with major smartphone and glass manufacturers because of the coatings’ ability to protect any glass-like material including mobile device screens.

The current product line includes MetaShieldPV for the solar energy industry, MetaShieldGLASS for consumer electronics applications and MetaShieldUV for aerospace markets. “The application and the principle is disruptive technology with seamless integration. We are mindful that the solar industry is a graveyard for companies that came up with different ideas that did not sell.

Those products always seemed to have a deficiency along the way, and we observed that most of the efficiency boost ideas (that failed) required changes in manufacturing or processing—that was their challenge.

“MetaShield represents practically zero change from what manufacturers are doing now. It is simply another coating that goes on before encapsulation. But it makes the cell more durable and it could increase efficiency 1 percent or more. It’s that easy,” he said.

Rise of Silica: Nanotechnology Innovation Creates Opportunity for Novel Product Development

23 February

Polymers (plastics) such as polyurethane and polystyrene have been the standard coating materials used in the design and development of products and equipment over the last several decades. We see and touch them numerous times on a daily basis. These coatings, while functional, have several deficiencies. Exposure to ultraviolet (UV) radiation causes photooxidative degradation, resulting in the breaking of polymer chains. We have all likely witnessed the destruction of these types of transparent coatings, often within a remarkably few years or months of application, despite all of the modern science of additives, designed to prevent the negative effects of UV light on polymers. Polymer coatings also have low resistance to abrasion, chemicals and extreme heat. In addition, these coatings have mediocre light transmission properties and often suffer from solarization and browning.

In stark contrast, the new breed of silica-based coatings represents an evolutionary advance over polymer-based offerings. Because silica is the primary material in glass, it shares the qualities of glass – superior transparency and toughness – yet has the flexibility and versatility normally associated with commonplace polymer coatings. These silica-based coatings also are highly resistant to UV degradation.

Silica-based coatings are also durable enough to be applied in thicknesses that would be far too low for any polymer to be effective. Although these coatings are glass based, their ultra-thin dimensions make them quite flexible, eliminating the main concern with glass, namely its fragility. Silica coatings have better light transmission, thermal properties, and acid resistance than traditional polymer coatings. Consistent with efforts by researchers worldwide to use eco-friendly materials, these coatings are also non-toxic and contain no fossil fuel elements, unlike their oil-based polymer counterparts. Silica coatings can also be tuned to provide a multitude of other benefits, such as abrasion resistance, omniphobicity, oleophobicity, and anti-reflectivity, to name a few.

Research and development divisions can leverage silica coatings’ ability to act as a durable and resilient host for functional materials, which when added to the surfaces of existing products, creates a variety of enhanced effects. Such functionality can be a game changer for the creation of products only feasible with this new glass-based coating. Some examples may include copper nanoparticles to reduce barnacle accumulation on nautical vessels and UV-blocking nanoparticles to mitigate radiation for both terrestrial and interstellar uses. For others, the added functionality allows for significant improvements to existing products, making them lighter, stronger and more durable.

Some companies, such as Enki technologies and DSM NV, have developed and used silica-based coatings as anti-reflective and soil-resistant coverings to improve solar photovoltaic panel efficiency. Companies such as Kristall and South Korea-based Ceko make scratch and oil-resistant, silica-based coatings offered to R&D pros within the automobile and cell phone markets, respectively. These R&D pros, in turn, use the coating to re-engineer a number of pieces used in the manufacture of these products. Other silica-based offerings also laud their hydrophobic and graffiti-resistant abilities.

U.S.-based MetaShield has created a silica-based coating that employs leading-edge nanotech principles to provide toughness and durability to a variety of substrates. Its 1 micron thick MetaShield coating meaningfully increases the mechanical strength of ordinary glass without adding size, weight or visible distortion. The company is in advanced-stage collaborations with major glass suppliers and mobile device companies to implement their glass strengthening technology in cell phones and other electronic devices.

As silica-based coatings gain acceptance, they enable research engineers and product developers worldwide to utilize materials that would otherwise not be practical due to their weak external durability. In the end, the main question is: How do plastic coatings compare with the new, nano-enabled glass coatings? Simply put, silica based coatings herald a significant disruption in the coatings market that has been dominated by waterborne polymers for the last half century.

Solar Power World: “Technologies Compete as Solar Cell Efficiency Race Continues.”

16 February

The continued quest for improved solar cell efficiency is vital to the growth of solar. Many companies are innovating ways to increase efficiency using a variety of technical approaches, not just because of the improved ROI great efficiency provides, but also because manufacturers need to differentiate themselves from the competition.

Kaneka recently achieved the world’s highest conversion efficiency of 26.33% in a practical size (180 cm²) monocrystalline silicon solar cell, breaking the previous record of 25.6% by ~0.7%. Natcore Technology achieved an efficiency of 19.4% in its most recent solar cell demonstration in November 2016. The laser-formed base contact is critical in the Natcore Foil Cell, which is an all-back-contact cell. Improving this contact has been a main focus of its research program as performance has been limited by higher resistance at this contact, as well as damage from the laser process. Natcore scientists have discovered a new, laser-based contacting process that overcomes these issues. Despite only a few runs with this new structure, the device efficiency increased by nearly 2% in fewer than six months (Natcore first announced an efficiency of 17.5% in June 2016).

MetaShield LLC has taken a different approach, developing a nanoparticle-based light trapping coating for PV triple junction solar cells that can improve the efficiency of a cell by up to 1.2% (absolute), when coated on top of the already-present anti-reflective coating.

U.S.-based wafer producer 1366 Technologies and Hanwha Q CELLS jointly hit a new record of 19.6% efficiency in December 2016 using 1366’s “direct wafer” process. The record, independently confirmed by the Fraunhofer ISE CalLab, was achieved using 1366’s kerfless, drop-in 156-mm multi-crystalline wafers and Hanwha’s Q.ANTUM PERC cell process. The previous record of 19.1% was achieved by the two firms one month earlier. According to a 1366 Technologies statement, the direct wafer process creates multi-crystalline wafers directly from molten silicon instead of taking several steps that require more energy and expense.

The principles of physics by which solar cells can be improved are limited, and solar cell manufacturers and their partners will be constrained by these principles at some point. However, the process by which they test these principles are closely guarded trade secrets that vary from manufacturer to manufacturer. In general, though, expect these solar cell suppliers and the technology firms working with them to focus on the following to improve efficiency further:

  1. Improved defect passivation at material’s surface and bulk to reduce charge carrier recombination.
  2. Reduced series resistance at contacts.
  3. Developing all back-contact solar cells to avoid light shading.
  4. Developing ways of trapping more light, such as better texturing, incorporating nanoparticles.
  5. Developing materials for broadband spectral shift to make use of wavelengths that solar cells cannot absorb currently.

Currently, monocrystalline silicon solar cells are close to their theoretical limit, which is about 30%. It has been theoretically predicted that spectral downshift and upshift can increase this limit to 40% and 50%, respectively. However, this technology is still in the early stage. Even though spectral shifts have been successfully shown in research labs, they cannot be used in solar cells yet. The materials discovered with spectral shifting properties so far absorb light in extremely narrow spectral range. In addition, the efficiency with which these materials perform spectral shift is very low.

While solar cell companies need to continuously improve solar cell efficiency, they also need to reduce manufacturing costs to remain profitable. In response, more solar cell manufacturers are increasing investments in research and development. Last year, Canadian Solar laid off 130 employees at its Ontario manufacturing plant in a variety of departments apart from its R&D group, which numbers approximately 350, and stated its intention of focusing more on R&D with a goal of finding new technologies it can bring to the market.

MetaShield is exploring ways to absorb the maximum number of photons available in the solar spectrum, including the study of plasmonic and dielectric nanoparticles because of their light trapping properties. In addition, the company is studying the spectral shift of solar spectrum to absorb the spectrum portion which is lost due to transmission or heat. Although enhancements due to plasmonic effects are minimal when the solar cell absorber layer is thick, it is expected that plasmonics-based technologies will accelerate the PV industry’s increasing use of thin-film solar panels, which have lower manufacturing costs.

MetaShield’s MetaShieldPV product leverages technology to produce more power with less balance-of-system. This increase in power makes marginal PV projects more cost effective.

“The enhancement provided by MetaShieldPV represents a five-year technological leap forward based on recent yearly average increases of around 0.2% for solar PV module efficiency,” said Martin Ben-Dayan, MetaShield’s founder and CEO, referencing a research report on solar cell efficiency improvements published by GTM Research in April 2014.

The installed price of solar energy has declined significantly in recent years as policy and market forces have driven more solar installations. The continued decrease in solar prices is unlikely to slow down anytime soon. Widespread adoption of plasmonics-based technologies can lead to low-cost solar panels that incorporate solar cells with a much thinner absorber material, using nanoparticles for optical enhancement. With solar already achieving record-low prices, the cost decline observed in 2015 indicates that the coming years will likely see utility-scale solar become cost competitive with conventional forms of electricity generation.

MetaShield Advanced Coating Technology Draws Interest at Defense Innovation Summit

1 February

Ability to Enhance Durability and Safety Could Improve Effectiveness of Materials and Equipment, and Lessen Reliance on Petroleum

NEW YORK/ST. GEORGE, Utah, Feb. 1, 2017 – Presentations of MetaShield LLC’s innovative new coating technology was met with strong interest at the recent Defense Innovation Summit, in Austin, Texas, last month. MetaShield scientists Jacob M. Schliesser and Puruswottam Aryal presented on the impact resistance and durability capabilities of its base MetaShieldTM coating and enhanced photo-conversion efficiency of its customized MetaShieldPVTM coating.

Schliesser, a materials chemist at MetaShield, presented “Impact Resistant Thin Film Coating Platform with Tunable Properties,” while Aryal, a project manager with a focus on thin film photovoltaics, presented “Nanoparticle Embedded Dielectric Anti-Reflective Coatings for Enhanced Photo-Conversion Efficiency of Triple Junction Solar Cells.”

Based on feedback from conference attendees which included representatives from the Department of Defense, military branches and defense industry suppliers – MetaShield™’s base coating could help increase the safety, lifespan, and durability of military material and equipment. They had a unique interest in the ability of a glass-based coating that can be applied easily at room temperature, which has historically been the main challenge for using such coatings. Because it is silica (glass) based, it has the superior transparency and toughness of glass, yet has the flexibility and versatility without any of the deficiencies normally associated with common polymer offerings.

According to attendees, the company’s solar offering, MetaShieldPV™, can assist the energy efficiency of U.S. military solar installations, and subsequently cut down on their petroleum needs. The transportation of petroleum is dangerous in militarized zones, resulting in the death of one U.S. soldier for every 50 petroleum transports.

“The Department of Defense is extremely interested in implementing ways to improve the safety and durability of material without adding any size or weight, which is what the MetaShield™ coating was designed to do,” said Martin Ben-Dayan, CEO of MetaShield, which has quickly become a leader in the advanced glass-based coating technology category. “There was also a good deal of interest in Schliesser and Aryal’s presentations and MetaShield’s ability to increase the efficiency of new and existing solar panel installations. We developed our nano-enabled technology to boost the efficiency of solar cells in general, but didn’t fully realize the military application. For military personnel in the field, saving energy means less fuel consumption, which means fewer dangerous fuel runs.”

Attendees at the Defense Innovation Summit were told about “tunable properties” of the baseline MetaShield formula. Because of the proprietary sol-gel chemistry in MetaShield™, functional nanoparticles can be added – to impart their qualities with a generally negligible effect on the physical and mechanical properties of the coating. MetaShield’s base coatings provide for improved impact resistance, enhanced UV protection, as well as scratch and corrosion resistance, among others.

In November, MetaShield conducted an independent research study indicating its proprietary MetaShieldPV™ nanotechnology coating can provide a 1.2 percent (absolute) efficiency boost for triple junction solar cells — representing a five-year technological leap forward based on recent yearly average increases of around .2% for solar PV module efficiency.

MetaShieldPV™ is a nanoparticle embedded glass-based coating that increases solar cell efficiency using advanced light trapping technology. The patent pending formula is spray coated directly onto the existing anti-reflective coating on the solar cells and hardens at room temperature, forming a transparent ~200nm glass film. The embedded nanoparticles employ strong forward scattering to affect optical enhancement in solar cells.

Research Study: MetaShieldPV Shatters Solar Panel Efficiency Forecasts with Innovative New Coating

14 November

Coating Provides 1.2 Percent Absolute Enhancement to Triple Junction Solar Cells


NEW YORK/ST. GEORGE, Utah, Nov. 14, 2016 – MetaShield LLC, a market leader in advanced glass-based coating technology, today announced an independent research study indicating its proprietary MetaShieldPV nanotechnology coating can provide a 1.2 percent (absolute) efficiency boost for triple junction solar cells.

“The enhancement provided by MetaShieldPV represents a five-year technological leap forward based on recent yearly average increases of around .2% for solar PV module efficiency, ” said Martin Ben-Dayan, MetaShield LLC’s founder and CEO, referencing a research report on solar cell efficiency improvements published by GTM Research in its PV Pulse publication in April 2014.

MetaShieldPV is a nanoparticle embedded glass-based coating that increases solar cell efficiency using advanced light trapping technology. The patent pending formula is spray coated directly onto the existing anti-reflective coating on the solar cells and hardens at room temperature, forming a transparent ~200nm glass film. The embedded nanoparticles employ strong forward scattering to affect optical enhancement in solar cells.

MetaShield commissioned the study with a grant from the Utah Science Technology and Research Initiative (USTAR) TAP program. The research was conducted at the MetaShield R&D facilities and verified by OAI-Optical Associates, a leading testing company in San Jose, Calif.

Key insights from the study concluded:

  • MetaShieldPV, when applied to triple junction solar cells, boosted their efficiency 1.2 percent (absolute). This increase amounts to the industry progress expected over five years by GTM Research, an analysis and advisory firm focused on the transformation of the global electricity industry, which predicted that efficiency of conventional solar panels is likely to improve by an average of about .2% annually.
  • In the study, triple junction GaInP/GaInAs/Ge solar cells, were coated with MetaShieldPV. The solar cells used were not encapsulated and already had commercial AR coatings. The current-voltage measurements (J-V curve) of the devices were measured under AM1.5 simulated solar spectrum illumination at OAI-Optical Associates, before and after the coating was applied. The comparison revealed an increase in device efficiency from 29.39 percent to 30.59 percent, an absolute increase of 1.2 percent.
  • Upon application, the product solidifies in air at room temperature and forms a thin film layer with refractive index of ~1.5. MetaShieldPV’s light-trapping coating employs plasmonic and dielectric nanoparticles to enhance the forward scattering of light incident on solar cells, and hence increase the short circuit current and the overall photo-conversion efficiency of these devices.

“MetaShieldPV is the result of several years of research and development,” said Glenn Mesa, MetaShield LLC’s director of R&D. “We’ve created a patented nanostructured composition that is capable of being custom infused with various nanoparticles, and forms a coating that is ultra-thin, ultra-light, with enhanced properties produced by the infused particles.”

According to Mesa, MetaShieldPV is in beta production and available to solar cell manufacturers.

The tested solar cells, also known as triple junction photovoltaics, are primarily used for interstellar vehicles and communication satellites, although also used in solar “farms” to generate electricity and augment power plants; for off-grid power (traffic, emergency and construction road signs); and rooftop solar panels. Because of their use in space, solar cells must be highly efficient and lightweight.

MetaShield has begun testing MetaShieldPV’s ability to provide a similarly dramatic enhancement to crystalline silicon photovoltaic cells.“The findings thus far indicate that results will be as good or better for the type of PV cells which currently encompass 90% of the $90 billion+ global solar photovoltaics market, which is currently struggling with very narrow margins and desperate for innovative solutions,” Ben-Dayan said.

MetaShield will release the results of the crystalline silicon PV study upon its completion.

It produces MetaShieldPV, MetaShieldGLASS and MetaShieldUV, for the solar PV, consumer electronics, and defense & aerospace markets respectively. The company’s base MetaShield formula, which is applied as a liquid using conventional coating methods and air-dries at room temperature, enjoys the durability and transparency of glass with the flexibility and versatility normally associated with polymer-based coatings.

Material Revolution

1 November


Over the last half century our electronics and communications have been transformed by the ‘Digital Revolution’. In the next half century, we will experience a ‘Material Revolution’ that will transform the physical world as we know it.

Nanotechnology enables mankind to create substances on an atomic scale that challenge the very fabric of what we hold to be true about the world and its properties. Concrete, stainless steel, and silicon made the modern era possible. Now a new class of materials are emerging, with far-reaching potential to transform the physical world and reorder the global economy.

In 2004 few knew of social media until Facebook launched a revolution. The same is true for the internet and Netscape, PCs and Microsoft, smartphones and Apple. For all of the companies working in nanotech, the industry does not have its ‘Facebook’. The reason is simple: nanotech does not yet have the ‘killer app’ that inspires the imaginations of people and industry, and defines its real world promise.

The promise of nanotechnology is innovation that amazes by seemingly disregarding the laws of nature. For example, MetaShield is a coating that is thinner than dust, yet makes glass up to 2x stronger. It goes on as a liquid, yet turns into glass. It can be infused with nanoparticles for enhanced effects, yet remains visually clear and transparent. We are developing many applications for this technology, with the ultimate goal of fulfilling the incredible potential of nanotechnology: revolutionary innovations that cause us to rethink our relationship with the physical world.

MetaShield™ Completes USTAR/TAP Grant

2 September

MetaShield LLC, a leading nanotechnology innovator in the field of glass based thin-film coatings, completed the Solar Enhancement Project grant from the Utah Science Technology and Research Initiative Technology Acceleration Program (USTAR/TAP). The company was selected out of a pool of 71 applicants based of based on its success with short circuit current and photo-conversion efficiency enhancement in triple junction solar cells.

On average, 10% of the light that enters a solar cell escapes without ever being used. MetaShield’s patent pending MetaShieldPV coating is a nanoparticle embedded formula that uses advanced light trapping technology to keep a portion of that light from escaping, thereby increasing overall solar cell efficiency. Recent tests have demonstrated device efficiency increase from 29.39% to 30.58%, i.e., by 1.19% (absolute) and short circuit current density (JSC) increase from 13.81 mA/cm2 to14.48 mA/cm2, i.e, by 0.67 mA/cm2 (or 4.85).

According to MetaShield CEO and founder Martin Ben-Dayan: ”With industry average efficiency gains of .2% per year, MetaShieldPV represents roughly a 5-year technological leap forward. This product can be spray coated and solidified at room temperature making for near-seamless integration into current PV manufacturing processes.”

MetaShieldPV is currently being adapted for use on crystalline-silicon cells, which currently comprise 90% of the $90+ billion market for solar PV. As the sources of fossils fuels like natural oil and coal are depleting, the solar industry is growing rapidly. At present, the U.S. has more than 25 gigawatts of installed photovoltaic capacity and generates about 0.73% of total U.S. electricity

MetaShield™ is a pioneer in glass based ultra-thin coating technology. It’s proprietary nanostructured formula doubles the break resistance of glass, and can also be infused with nanoparticles for enhanced effects. Sprayed on as a liquid, the formula hardens at room temperature into a sheet of glass that is approximately 50 times thinner than a human hair. Since it is glass based, it has superior transparency and durability, yet has the flexibility and versatility normally associated with commonplace waterborne polymer coatings.

MetaShield™ is also a robust and resilient delivery vehicle for nanoparticles that can give ordinary objects extraordinary abilities, without adding size or weight. Nanoparticles tailored to multiple industry uses and applications are seamlessly incorporated, making MetaShield™ a highly scalable “wonder material”.

MetaShield LLC (www.metashield.com), founded in 2011, is a nanotechnology company based in New York City with research and production facilities in St. George, Utah. It produces MetaShieldPV, MetaShieldGLASS and MetaShieldUV, for the solar, consumer electronics, and UV mitigation markets respectively.

MetaShield™ Anticipates Availability of Beta Product Launch Q1 2017

26 July

The anticipation is building at MetaShield’s research and production facilities in Saint George, Utah. The breakthrough nanotechnology company is preparing for the release of their beta product, MetaShield, a highly scalable and cutting edge glass-based coating technology. The company has been working with Fortune 50 companies on collaborative testing for the coating formula which is set for beta production in Q4 2016.

The proprietary nanostructured formula increases break resistance by making glass twice as strong with virtually no added weight. The designed technology is applied as a liquid and hardens into ultra-thin and flexible sheet of glass that has the ability to absorb and diffuse impact using a complex matrix of nanoparticles.

According to MetaShield’s CEO and founder Martin Ben-Dayan: “MetaShield fulfills nanotechnology’s fundamental promise of doing more with less; less size, less weight, and less cost. MetaShield’s advanced coating technology changes the behavior of underlying materials without changing their weight dimensions by incorporating attributes without adding size weight or dimension”.
