We performed Reverse Monte Carlo analysis (RMCA) to study amorphous structure of a heterofullerene, CN by using pulsed neutron powder diffraction data. The scattering function S(Q) shows that the structure is amorphous, while the atomic pair distribution function (PDF) shows that the local structure is similar to that of C
. Obtained structures strongly depend on the initial models. Problems for this RMCA method are discussed.

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.

The effects on proton and electron irradiateions of the characteristics of InGaP/GaAs/Ge triple junction designed for terrestrial application were studied. The solar cells used in this study has a 1% In-contained GaAs middle sub-cell, and their efficiency is more than 30 % under AM1.5, which is the highest efficiency of all solar cells in the world.As the results of 1MeV-electron and 10 MeV-proton irradiation, terrestrial triple-junction sole cells were found to have the same radiation resistance as space single junction GaAs solar cells, although terrestrial triple-junction solar cells is not stronger than space triple-junction solar cells made in USA. As the result of proton energy dependence of the electrical characteristics and quantum efficiency, the strong degradation of the GaAs middle cell was observed.

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).
