Abstract

Embodiments of this application provide a perovskite solar cell, a preparation method thereof, and an electric device. The perovskite solar cell includes: a back plate; a transparent substrate, where a sealed cavity is formed between the transparent substrate and the back plate; and a perovskite solar cell device, where the perovskite solar cell device is located in the sealed cavity; where the sealed cavity contains ammonia gas having a volume fraction of 10%-100% and residual inert gas. The 10%-100% ammonia gas can improve chemical stability of a perovskite material, thus improving thermal stability of the perovskite solar cell device, and further improving efficiency and service life of the perovskite solar cell.
