Abstract

Recent advances in Spectrolab's high efficiency III-V multi-junction space solar cells are reported. The latest generation GaInP/GaAs/Ge solar cells under production - the Ultra Triple Junction (UTJ) - have an average efficiency at maximum power of 28-0% (AM0, 28°C, 1353mW/cm2) at beginning of life (BOL), and 226% at 60° C at end of life (EOL, 15 years in GEO orbit). This represents a 55% relative higher efficiency at EOL, compared with the previous generation Improved Triple Junction (ITJ) cells. The P/P0 - for 1 MeV electrons after 1015 cm-2 fluence has also improved to 0·86, compared with 0·84 for the ITJ cells. These and other performance results of UTJ solar cells are reviewed in comparison with ITJ solar cells.
