The invention belongs to the technical field of batteries, and relates to a perovskite battery interface passivation method. The preparation method comprises the following steps: dropwise adding a nickel oxide solution on an ITO substrate, uniformly spin-coating, and then drying, so that a nickel oxide nano-particle layer is cured; dropwise adding an ammonium polyphosphate solution on the cured nickel oxide nano-particle layer, and drying after uniformly spin-coating; coating the perovskite precursor solution on the surface of the ammonium polyphosphate layer of the substrate by adopting a two-step spin coating method, and annealing to complete the preparation of the perovskite layer; preparing an electron transport layer on the perovskite layer; and preparing a gold electrode on the electron transport layer. Ammonium polyphosphate is adopted for passivation of the upper interface and the lower interface of perovskite, phosphate groups of the lower interface and Ni < 2 + > / Ni < 3 + > form a strong coordination structure, a stable buried interface is formed, iodine vacancy forming energy is enhanced, defect states of the lower interface of the film are reduced, phosphate groups of the upper interface can be bonded with uncoordinated Pb < 2 + >, and therefore the defect states of the upper interface of the film are reduced, and the performance of the film is improved. The upper interface and the lower interface of the perovskite solar cell are good in dispersity.
