| Abstract: | The CuInSe2 absorber was synthesized by non-vacuum process with a simple and low-cost method, which fabricated absorber layer of thin-film solar cell. The extra amount of Se was added into the ink to help reduction of the oxide and solid Se fountain was used to provide Se atmosphere during the selenization progress. The influence of same factors was investigated, such as the time of reduction in H2, the time of selenization and the Se vapor pressure. The selenizaion, processed at 550 °C for 60 min with the Se vapor pressure at 1.90 kPa, resulted in high quality CuInSe2 layer with very good chemical composition. |
