The invention discloses a method for preparing a flexible copper indium gallium selenide/perovskite stacked solar cell, which belongs to the technical field of solar cells and energy. The flexible copper indium gallium selenide/perovskite tandem solar cell of the present invention is sequentially composed of a stainless steel foil (SS) substrate (1), a metal back electrode (2), a copper indium gallium selenide absorbing layer (3), and a CdS buffer layer (4), a window layer (5), an intermediate compound layer (6), a hole transport layer (7), a perovskite phase absorption layer (8), an electron transport layer (9) and a transparent electrode (10). The battery with this structure is conducive to the balanced extraction of charges, suppresses the hysteresis effect of the current-voltage curve, and improves the filling factor and photoelectric conversion efficiency of the battery; and the all-inorganic material structure improves the working stability of the battery. The copper indium gallium selenide layer is prepared by magnetron sputtering and selenization, and the perovskite layer is prepared by spraying and semi-vapor deposition. This method is beneficial to large-scale production and preparation of large-area solar cells. |
