The electrical performance of Cu(Ga,In)Se solar cells on MDS-1 which was launched in February 2002 was measured. The CIGS solar cells show superior radiation resistance in space. The short circuit current dose not degrade and the open circuit voltage shows only 1 % degradation after 200 days. On the other hand, in the case of ground test, the recovery of electrical performance of CIGS solar cells are observed at RT. And, the recovery is enhanced by current-injection.

Recovery of electrical characteristics of Cu(In,Ga)Se irradiated with protons was studied. A proton irradiation chamber which has a AM0 solar light was used for in-situ measurement in this study. The electrical characteristics of irradiated samples which were kept under a dark condition recovered. Furthermore,this recovery effect was enhanced by light illumination. The activation energy for the recovery was estimated to be 0.80 eV (light illumination case) and 0.92 eV (dark condition case).
