▎ 摘 要
NOVELTY - The utility model claims a cadmium sulphide as perovskite thin film solar battery of the window material, wherein the structure of the solar cell from down to up as the transparent conductive substrate 1, an N-type cadmium sulfide film 2, P-type perovskite film 3, P-type heavy-doped graphene film 4, metal electrode 5. The utility model has the following advantages: on one hand, using cadmium sulphide good window effect and as electron selective contact layer capable of photoelectric conversion efficiency greatly improved perovskite solar cell, on the other hand, heavily doped graphene has high carrier mobility and electric conductivity, the compact structure can effectively prevent degradation in the air by the water oxygen perovskite film and barrier metal electrode to harmful diffusion of perovskite film, greatly improves the stability and the photoelectric conversion efficiency of the conventional perovskite solar cell.
