The improvement of the efficiencies of thin silicon solar cells for space use was studied. The representative 3 types of non-reflective surface structures were evaluated and their characteristics were clarified. Solar cells with these structures showed excellent electrical performance and the best result of 18.0 % efficiency for 100 micron thick cells was attained. Cells made from 2 Ohm substrates showed higher electrical performance and radiation hardness than those from 10 Ohm substrates. The electron irradiation tests showed that the current degradation of the cells with lower resistivity substrates were reduced and the improved solar cells can be used for future satellites.
