The invention belongs to the technical field of solar cells, and discloses a method for passivating perovskite and a preparation process for perovskite solar cells. In the invention, the defects on the surface of the perovskite film are passivated by introducing an organic ammonium hexafluorophosphate, and a method for forming an organic ammonium hexafluorophosphate passivation layer on the surface of the perovskite film; the perovskite layer is passivated During processing, the organic ammonium hexafluorophosphate can bond with the dangling bonds in the perovskite absorber layer, effectively passivate the defects on the perovskite surface, and further enhance the perovskite solar cell. The perovskite solar cells of this passivation perovskite method have the advantages of high efficiency, stability and low cost. The development of such preparation technology provides a new device preparation strategy for the commercial application of perovskite solar cells. |
