Title:
PEROVSKITE THIN FILM, SEED CRYSTAL-ASSISTED FILM FORMING METHOD, AND PEROVSKITE SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2024/031752
Kind Code:
A1
Abstract:
The present application relates to the technical field of solar cells, and in particular to a perovskite thin film, a seed crystal-assisted film forming method, and a perovskite solar cell. A first aspect of the present application provides a perovskite thin film, comprising a base and a perovskite thin film layer bonded to the surface of the base, wherein the perovskite thin film layer is formed on the base by a mixed solution containing all-inorganic perovskite quantum dots and a perovskite precursor solution. Under the synergistic effect of the all-inorganic perovskite quantum dots and the perovskite precursor solution, the defects of the perovskite thin film can be overcome. The perovskite thin film layer of the present application has the prospects of being applied to other fields of photoelectric information functional materials, such as photoelectric detectors, LED light-emitting devices, and field effect transistors. In the film forming process of the mixed solution of the perovskite precursor solution, the all-inorganic perovskite quantum dots serve as seed crystals, and can induce the crystallization and rapid film forming of the mixed solution, thereby solving the problem that the forming of perovskite thin films is difficult and is low in efficiency.
