SCHOTT® Solar Glass
SCHOTT solar cell cover glass provides solid protection for high-performance solar cells. By combining lightweight, extremely durable materials with outstanding optical transmittance, SCHOTT® Solar Glass cover glass ensures reliable power supply and and efficient operation of photovoltaic systems over a long period of time – both in daily use on Earth and in demanding missions in space.
Exceptional clarity for lasting photovoltaic performance
Whether in orbit or on Earth, SCHOTT® Solar Glass keeps light working at its best. Its high and stable optical transmittance ensures that solar cells and reflectors capture maximum energy, while advanced UV filtering and solarization resistance maintain clarity over years of exposure. The result is dependable, long-term power generation across every environment.
Engineered protection for demanding environments
From launch vibration to desert heat, SCHOTT® Solar Glass is built to perform. Available in a range of thicknesses down to around 30 µm, it combines low weight with outstanding strength and durability. Fire-polished surfaces, robust edges and precise thermal matching protect solar cells and reflectors from stress, radiation and temperature extremes, delivering long-term reliability for photovoltaic and optical systems worldwide.
Reliable, protective and built to last
SCHOTT® Solar Cell Cover Glass combines high optical performance with long-term material stability for both space and terrestrial use. It offers excellent transmittance from UV-A to near-infrared while effectively blocking low-wavelength UV radiation that can degrade adhesives and cell interfaces. Low solarization ensures stable efficiency over extended operation, and reliable protection against high-energy particle radiation preserves optical clarity and structural integrity throughout the glass lifetime.
Outstanding transmittance
High light transmittance from UV-A to near-infrared supports efficient power generation and optical performance.
High absorption of UV radiation
Effectively blocks low-wavelength UV to protect adhesives and sensitive cell layers from degradation.
Made to withstand UV solarization
Retains optical clarity and consistent transmittance even after long exposure to radiation and sunlight.
High edge strength
Precisely cut and strengthened edges resist cracking and mechanical stress during handling and launch.
Protection from high-energy particles
Acts as a barrier to energetic particles, preventing cell damage and maintaining stable performance.
Available in large formats
Offered in a wide range of sizes and thicknesses for flexible integration into solar and optical systems.
Reliable performance for the lifetime of a mission
