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.

摘要:
通过非真空工艺利用CuO、In2O3混合氧化物制备CuInSe2薄膜太阳能电池中的吸收层CuInSe2薄膜. 利用柠檬酸法制备出粒径在100 nm以下的CuO、In2O3混合氧化物纳米粉,在浆料中加入过量的硒,用来创造非平衡的反应条件促进氧化物的还原和硒化. 考察了影响硒化的几个反应条件,最优的硒化条件为1.9 kPa的Se蒸汽压中,550 °C硒化60 min.
