We have developed high-efficiency homojunction 1 cm × 2 cm InP space solar cells by diffusing In_2S_3 into p type InP substrates and investigated their fundamental characteristics such as electrical and mechnical characteristics and thermal properties. On the radiation resistant mechanism of InP cells, we have studied InP cells fabricated at NTT Laboratories and found superior properties such as room temperture annealing and minority carrier injection enhanced annealing phenomena for radiation-induced defects in InP crystals with 1 MeV electron irradiation. We have also found that InP cells are superior to Si and GaAs cells in radiation resistance owing to the e...
