Abstract :
Thin-film CIGS solar cells have been investigated for use in the space environment. The study includes deposition on lightweight metal substrates, measurement under AMO light, and irradiation by electrons and protons. A 15.2% AMO cell performance has been achieved, resulting in a specific power of 1433 W/kg and 1235 W/kg for bare and SiOx “coverglass” cells, respectively. No degradation has been observed after e- irradiation. A 24-cm2 cell design has achieved 1100 W/kg specific power
