The invention relates to the field of solar cells, in particular to a preparation method of a perovskite solar cell based on interface modification. The method comprises the following steps of: taking uniformly deposited indium tin oxide (ITO) glass as a cell anode, depositing a layer of mixed film of PTAA and F4-TCNQ on the indium tin oxide (ITO) to serve as a hole transport layer; spin coating a mixed solution of PMMA and F4-TCNQ on the hole transport layer to prepare an ultrathin passivation layer as an interface passivation layer, depositing a perovskite active layer on the interface passivation layer to serve as a photosensitive layer, depositing a layer of [6, 6]-phenyl C61-methyl butyrate PC61BM on th |
