SCHOTT, a Germany-based specialty glass manufacturer, has launched a solar cell cover glass for space applications. The product has been jointly developed with AZUR SPACE Solar Power and supported by the European Space Agency and the German Aerospace Center. According to the announcement, the cover glass is intended for next-generation satellite solar cells requiring high radiation resistance and optical stability. It has been engineered to support silicon cells and III-V multijunction solar cells used in modern satellite power systems. The material is designed to maintain optical transmission performance under prolonged radiation exposure and extreme thermal conditions. A coefficient of thermal expansion of 6.9 × 10⁻⁶ K⁻¹ has been matched to GaAs solar cells to reduce mechanical stress. Qualification is being conducted in line with European Cooperation for Space Standardization (ECSS) standards.
