MetaShield™ is a highly scalable wonder material for a multitude of industry uses, along the lines of Teflon, GoreTex, Kevlar, etc.  While constantly innovating and exploring its vast potential, we are currently in beta production of the following:

GLASS

MetaShieldGLASSTM

  • Enhances break resistance 
  • Ideal for smart device cover glass, windows, eye protection, etc.
  • User friendly application
  • Thin layer, adds negligible mass or size.
  • Approximately 1 - 5 microns thick

In the time it takes to read this sentence, 6 cell phone screens will have shattered worldwide.  MetaShield is an ideal solution for the $8.6 Billion market for smart device cover glass, and many others as well.

MetaShield is a breakthrough silica-based coating that combines the transparency and durability of glass with the flexibility and versatility normally associated with polymers.  This technology is ideal for enhancing the break resistance properties of transparent substrates such as smart device screens, windows, protection gear, etc.

Rapid force exerted during impacts cause the MetaShield coating to 'tense-up' allowing it to absorb more shock.  Existing technologies require the use of thick laminates and/or expensive processing to produce stronger transparent materials.  MetaShield, on the other hand, is capable of enhances the break resistance objects that are already in use, with a durable coating that adds negligible mass or size.

MetaShield can also be applied at room temperatures using conventional spray coating methods.  Our simple, user friendly application is a significant advance on current silica application technologies such as vapor deposition, baking, sputter coating, etc, resulting in substantial savings of industry and government resources.

SOLAR

MetaShieldPVTM

  • Embedded with plasmonic nanoparticles
  • Advanced 'light trapping' technology
  • 1.2% absolute efficiency increase on AR coated triple junction PV’s
  • Refractive index of ~1.5
  • Approximately 100 nanometers thick

 

On average, 10% of the sunlight that enters a solar cell bounces around inside of the cell and eventually escapes.  MetaShield PV's innovative strong forward scattering technology keeps some of that light from escaping, thus boosting overall efficiency.  This 'light trapping' is achieved using special nanoparticles embedded in the flagship MetaShield formula.

The company was recently awarded a grant by the Utah Science Technology and Research Initiative (USTAR), based on its success with short circuit current and photo-conversion efficiency enhancement in triple junction solar cells based on GaInP/GaInAs/Ge absorber layers.  The formula is easily spray coated directly on top of the existing anti-reflective coating, and dries quickly at room temperature.  Recent tests have demonstrated a 1.2% absolute efficiency increase, and short circuit current density (JSC) increase of 4.85%. 

Adaptation is currently underway for crystalline silicon cells, which currently comprise nearly 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 PV technology can produce more power with less BOS which directly benefits EBITDA and can push countless marginal PV projects over the line to make the numbers work.

UV

MetaShieldUVTM

  • Embedded with UV-blocking nanoparticles 
  • Transparent
  • Blocks up to 80% of UV transmission
  • Withstands extreme radiation and temperatures
  • Possible replacement for satellite PV cover-glass
  • Approximately 16 microns  thick and extremely lightweight, ideal for aerial and interstellar uses

Coatings enhanced with UV-blocking nanoparticles have shown great promise for providing ultrathin protection to a number of UV-sensitive devices and materials including solar cells, wood, polymers, and more.  We have developed a novel process that easily incorporates UV-blocking nanoparticles into our flagship MetaShield coating.

MetaShieldUV is a glass-based coating that combines the transparency and durability of glass with the flexibility and versatility of polymers, all while curing at room temperature under ambient conditions.  Our patent-pending process allows for the inclusion of UV-blocking nanoparticles with very uniform dispersion while maintaining high transparency in the visible range once cured.  This coating is compatible with a wide range of materials and can be applied in as little as one hour from start to finish.  MetaShieldUV has demonstrated tolerance to temperatures as low as -190c and as high as +150c.

MetaShieldUV thin-film offers an advanced, simple, and robust alternative to the $8 Billion market for UV coatings that is currently dominated by inferior "thick glass" and polymer-based product offerings.
