Abstract
A perovskite solar cell includes a perovskite layer comprising a first surface and a second surface that are opposite each other in the thickness direction thereof; a hole transport layer provided on the first surface; and an electron transport layer provided on the second surface. The electron transport layer comprises at least two sub-layers and a doping material, and each of the sub-layers has a conduction band bottom energy level lower than that of the hole transport layer and a valence band top energy level lower than that of the hole transport layer.
