The invention discloses a doped perovskite thin-film solar cell and a preparation method thereof. The doped perovskite thin-film solar cell includes a transparent conductive substrate and an electron transport layer, a mesoporous titanium dioxide layer, a perovskite light-absorbing layer, a hole transport layer and an electrode sequentially stacked on the surface of the transparent conductive substrate. The perovskite light-absorbing layer material is halogen-doped tin perovskite, and the halogens are mainly Br and I. The preparation method comprises the steps of sequentially forming an electron transport layer, a mesoporous titanium dioxide layer, a tin perovskite layer, a hole transport layer and an electrode on the surface of a transparent conductive substrate. The doped perovskite thin-film solar battery of the invention has no environmental pollution, strong light absorption ability and high photoelectric conversion efficiency. The preparation method has the advantages of simple process and easy operation, high production efficiency and reduced production cost. |
