Abstract

In 2001 Spectrolab completed design and qualification, and began production on the third-generation multijunction solar cell - the improved triple-junction GaInP₂/GaAs/Ge. With over 21% AMO conversion efficiency at an operating temperature of 60°C at end-of-life, this cell has 16% more power than competing dual-junction designs in GEO orbit after 15 years (7 × 10₁₄ 1-MeV electron equivalence), Spectrolab is currently qualifying the fourth-generation triple-junction solar cell capable of delivering over 22% AMO conversion efficiency under these same conditions, with a beginning-of-life operating efficiency of 28%.
