Embodiments of the present invention provide a perovskite precursor, a perovskite and a solar cell, wherein the perovskite precursor is composed of an asymmetric organic bisamine halide salt, an organic component, an inorganic component, an additive and an organic solvent mixed to get. In the present invention, the perovskite precursor is prepared by adding an asymmetric organic bisamine halide salt, so that the perovskite formed based on the perovskite precursor has better stability under moisture, light and heat, so that The solar cells assembled from the perovskite can achieve both stability and photoelectric conversion efficiency. |
