摘要

Prototype Inverted Metamorphic (IMM3J) cells were grown and fabricated and assembled onto an experimental flight coupon for inclusion on the 7th Materials International Space Station Experiment (MISSE-7). This paper examines the first eleven months of on-orbit data of prototype IMM3J solar cells in a low earth orbit (LEO) environment. The prototype IMM3J solar cells show excellent electrical and mechanical stability over the first eleven months in orbit with 97-98% in Jsc and maximum power (Pmp) retention for the four actively measured IMM3J solar cells. The loss in Jsc and Pmp is likely due to etching of the anti-reflective glass cover coating due to atomic oxygen.
