The invention discloses a translucent perovskite solar cell and a preparation method thereof. The perovskite solar cell comprises a transparent conductive substrate a, an inorganic electron transport layer, a light capture layer, an inorganic hole transport layer and a transparent conductive substrate b, wherein The light-harvesting layer is formed of DXZ type 3 perovskite material, D is selected from Cs + , CH 3 NH 3 + , CH(NH 2 ) 2 + or a mixture thereof, X is selected from Pb 2+ , Sn 2+ , Ge 2+ or a mixture thereof, Z is selected from Cl - , Br - , I - or a mixture thereof. The perovskite solar cell prepared by adopting the all-inorganic material as the electron transport layer and the hole transport layer in the present invention abandons the disadvantages of high cost and damage stability of the organic material, and greatly improves the stability of the battery. At the same time, the present invention adopts the physical extrusion method to prepare perovskite solar cells, the preparation process is extremely simple, and the perovskite film also has good uniformity; the cost is low, and solar cell devices with excellent performance and stability can be obtained, which is beneficial to calcium Commercial application of titanium oxide solar cells. |
