Abstract

A method of fabricating a perovskite solar cell includes forming a hole transport layer on a transparent electrically conductive substrate, and forming a perovskite layer on the hole transport layer via a two-stage vacuum evaporation process. Then, an electron transport layer and an electrode layer are formed in order. The two-stage vacuum evaporation process includes first vacuum evaporating a first material on the hole transport layer and then vacuum evaporating a second material on the first material so as to react the first material with the second material in situ and form the perovskite layer.
