Abstract

The present application discloses a perovskite layer, a method for preparing a perovskite layer, a perovskite-layer solar cell and a perovskite-layer-solar-cell assembly, which relates to the technical field of photovoltaics, and is used to prepare a perovskite layer that can completely cover the substrate and has few defects. The method for preparing a perovskite layer includes: providing a substrate; forming perovskite seed crystals on the substrate; soaking the perovskite seed crystals into a perovskite solution; by the effect of the perovskite seed crystals, the perovskite seed crystals growing into a perovskite thin film; and performing annealing treatment to the perovskite thin film, to form the perovskite layer. The perovskite layer and the preparing method thereof according to the present application are used for the fabrication of a solar cell.
