The conversion efficiency of CIGSe solar cells has reached 23.6% through improvements in bulk quality and buffer interface quality. To further improve the conversion efficiency, we propose the insertion of Li-doped NiO (NiO) into the rear contact of CIGSe solar cells. In this presentation, we report on NiO thin films deposited by sputtering without a pressure gradient and by pressure-gradient sputtering, and investigate the sputtering-power dependence of their properties.
