Abstract

A perovskite solar cell, a preparation method therefor and a power consuming device are provided. In some embodiments, the perovskite solar cell of the present application has, in order, a back electrode, a hole transport layer, an interface passivation layer, a perovskite layer, an interface passivation layer, an electron transport layer, and conductive glass, wherein the HOMO energy level of an interface between the perovskite layer and the interface passivation layer is 0.01-0.4 eV, and the energy band gap between the HOMO energy level and the LUMO energy level is 0.01-0.4 eV; and the interface passivation layer contains: an organic amine salt of a biphenyl compound and/or an organic amine salt of an acene compound. In the perovskite solar cell according to the present application, by passivating the perovskite layer therein with an organic amine salt of a biphenyl compound or acene compound, the VBM of the perovskite layer is improved, facilitating the extraction of holes, and the transport efficiency of carriers is improved, so that the efficiency and stability of the perovskite solar cell can be greatly improved.
