An overview of photovoltaics for space applicationsSignificant progress in both silicon and GaAs technology for photovoltaic applications has been made. As a result 50 micron silicon cells, incorporating all the recent processing advancements, have been produced which deliver over 19 mW/sq cm initial power. These cells also display impressive performance after exposure to 1 MeV electrons, delivering 15 mW/sq cm after a fluence of 1 x 10 to the 15th e/sq cm. GaAlAs cells are now being made which have conversion efficiencies and radiation resistance superior to the best silicon solar cells. A discussion of the work that led to this situation, as well as an attempt to project further progress in both silicon and GaAs technology is given.
