| Research Abstract |
This research was aimed to develop high efficient solar cells (SC) using a low-cost and an energy saving process. We selected CuInS2(CIS) and γ-In2Se3as candidate materials for tandem type SC, since this combination is expected to have the highest theoretical conversion efficiency. It was found that the electrical properties of these materials can be controlled by the proper selection of impurities. The CIS pn homo-junction SC and the γ-In2Se3/CIS hetero-junction SC were fabricated on the basis of these results. The maximum efficiency was about 1%. Though the tandem type SC is not achieved, the important and basic results have been obtained for the realization
