A new chapter in solar cell protection is about to begin
Meet us live

The next generation of solar cell protection is ready to take off.

The space economy is accelerating fast, with satellites now counted in the tens of thousands. Nearly all depend on photovoltaic cells to generate energy – yet in orbit, these cells face relentless stress: thermal cycles from -150°C to +150°C, charged particle radiation, and atomic oxygen.

Cover glass turns fragile efficiency into lasting power. Serving as both filter and shield, it protects against harmful radiation while allowing maximum light to reach the solar cell. Without this protection, efficiency fades – risking the power that missions rely on.

Proven heritage

Decades of expertise in glass manufacturing enable SCHOTT to produce solar cell cover glass in ultra-thin formats – down to UTG thicknesses below 70 µm – with additional coating options for enhanced performance.

Thanks to this foundation, SCHOTT solar cell cover glass has rapidly established itself as a vital element of satellite power protection in orbit.

Key advantages of new generation

    High optical transmission

    Over 92% transmittance in the UV-A to near-infrared spectrum, aligned with the sun’s spectrum.

    Radiation shielding

    Proven protection against harmful UV, reduced solarization, and support for long-term stability in orbit.

    Mechanical resilience

    Fire-polished surfaces, outstanding homogeneity, and durability against thermal cycling and atomic oxygen.

    Ultra-thin, lightweight formats

    Available from 50–150 µm, balancing ultra-low weight with robust protection.

    Tailored for multijunction cells

    A coefficient of thermal expansion (CTE) engineered for advanced multijunction cells ensures long-term stability and reliability in orbit.

    Scalable by design

    Large formats, cut-to-size substrates, and optional coatings such as anti-reflective layers unlock flexibility across array architectures.
    Ready for take-off

    At Space Tech Expo Europe (18.-20. November 2025, Booth # H60), SCHOTT will unveil the next step in solar cell cover glass. From protecting what matters to delivering what counts.
