Document Type and Number:
WIPO Patent Application WO/2022/218089
Kind Code:
A1
Abstract:
Embodiments of the present application provide a perovskite solar cell and a preparation method therefor, and an electrical device. The perovskite solar cell comprises: a backplate; a transparent substrate, a sealed cavity being formed between the transparent substrate and the backplate; and a perovskite solar cell device located in the sealed cavity, wherein the sealed cavity contains ammonia gas having a volume fraction of 10%-100% and a balance of inert gas. The 10%-100% ammonia gas can improve the chemical stability of a perovskite material, thereby improving the thermal stability of a perovskite solar cell device and further improving the efficiency and service life of a perovskite solar cell.
