Recent advances in crystalline solar cell technology are reviewed. Dual-junction and triplejunction solar cells are presently available from several U. S. vendors. Commercially available triple-junction cells consisting of GalnP, GaAs, and Ge layers can produce up to 27% conversion efficiency in production lots. Technology status and performance figures of merit for currentlyavailable photovoltaic arrays are discussed. Three specific NASA mission applications are discussed in detail: Mars surface applications, high temperature solar cell applications, and integrated microelectronic power supplies for nanosatellites.
