The application discloses a multifunctional additive modified inverted perovskite solar cell. The structure of the cell is composed of a bottom electrode, a hole transport layer, a modification layer, a perovskite light absorption layer, an electron transport layer, a buffer layer and a counter electrode from top to bottom. The modification layer is made of one or two of PEAI, Cl-PEAI and F-PEAI. The perovskite light absorption layer is a perovskite containing 2-hydrazinobenzothiazole modification, and the doping amount of 2-hydrazinobenzothiazole in the perovskite active layer is 0.01-10wt%. The application effectively improves the photoelectric conversion efficiency of the perovskite solar cell, exhibits excellent photoelectric conversion performance, and has a wide and good application prospect.
