Space solar cell

摘要

Disclosed is a solar cell for use in space, comprising compound semiconductors used as photovoltaic conversion material. The solar cell comprises a cover glass used for improving the radiation tolerance as a substrare for thin film deposition. The solar cell further comprises a crystalline thin film of the compound semiconductors directly formed on a surface of the cover glass for acting as the photovoltaic conversion material. The crystalline thin film of compound semiconductors is formed using a metal organic chemical vapor deposition system.
