Solar Cell Cover Glasses

The main goal of our Solar Cell Cover Glasses is to offer effective protection for space and terrestrial photovoltaics. As the world increases its reliance on solar power to generate electricity, the use of photovoltaics is becoming more widespread – not only on Earth but in space.

Reliable protection against harmful radiation

Whether on Earth or in space, photovoltaics require technical solar glass for protection from harsh environments, as well as to sustain high transmittance in the visible spectrum of light up to near-infrared that increases the efficiency of the cell while shielding against harmful radiation.

Flexible design to suit your mission

SCHOTT’s decades of experience and expertise in glass manufacturing allows Solar Cell Cover Glass to be produced in different thicknesses directly drawn from the melting tank. This includes ultra-thin and flexible glass available down to UTG thicknesses below 70 µm as cut-to-size substrates. Design opportunities are further enhanced by the availability of different coatings.

Stable, protective and long-lasting

Our Solar Cell Cover Glasses offer a range of technical advantages when used for space or terrestrial applications such as photovoltaic systems and optical solar reflectors. Transmittance across the spectrum from UV-A to near-infrared is excellent, while low-wavelength UV radiation is effectively blocked. Low solarization also ensures reliable performance during the lifetime of a mission, while a fire-polished surface and outstanding geometrical homogeneity add to its effectiveness.
