Cu2 ZnSnS4/Zn(O,S)异质结薄膜太阳电池的数值仿真
Numerical simulation Cu2 ZnSnS4/Zn( O, S) heterojunction thin film solar cells
摘要
Abstract
In this paper CZTS solar cell with a structure of CZTS/Zn( O, S)/Al:ZnO was simulated by solar cell capacitance simulator ( SCAPS) . The impacts of band gap, electron affinity, thickness, donor concentration of Zn(O, S) and operating temperature on the performance of CZTS solar cells were investigated. It has been obtained that the optimum thickness of Zn( O, S) is about 50 nm. The suitable doping concentration of Zn( O, S) is around 1017 cm-3 . The temperature coefficient of efficien-cy is about -0.021% K-1 in the CZTS solar cell. All these simulation results will provide some impor-tant guidelines for fabricating high efficient CZTS solar cells.关键词
