The invention provides a flexible antimony selenide/perovskite tandem solar cell, comprising a substrate, a back electrode, an antimony selenide absorption layer, a buffer layer, a window layer, an intermediate composite layer, a hole transport layer, Perovskite absorption layer, electron transport layer and conductive electrode; the material of the intermediate composite layer is selected from one or more of molybdenum oxide, indium tin oxide, zinc oxide, aluminum-doped zinc oxide, tin oxide and C60. Compared with the prior art, the present invention combines a plurality of light absorbers with different band gaps to form a multi-junction solar cell, which can not only broaden the utilization range of the solar spectrum, but also reduce the thermal relaxation loss of photogenerated carriers, thereby improving the performance of the solar cell. Photoelectric conversion efficiency of solar cells. |
