OverviewTypes of solar cells typically usedHistoryUsesImplementationIonizing radiation issues and mitigationSpacecraft that have used solar powerFuture uses

Up until the early 1990s, solar arrays used in space primarily used crystalline silicon solar cells. Since the early 1990s, Gallium arsenide-based solar cells became favored over silicon because they have a higher efficiency and degrade more slowly than silicon in the space radiation environment. The most efficient solar cells currently in production are now multi-junction photovoltaic cells. These use a combination of several layers of indium gallium phosphide, galli
