Abstract

A tandem cell and a manufacturing method thereof are provided in the present disclosure, so as to improve hole transmission performance of the tandem cell. The tandem cell includes a bottom cell, a hole transporting layer formed on the bottom cell, a perovskite absorbing layer formed on the hole transporting layer, and a transparent conducting layer formed above the perovskite absorbing layer. A material of the hole transporting layer includes a semiconductor material with a p-type delafossite structure, and a valence band top energy level of the hole transporting layer sequentially decreases in a direction away from the bottom cell, which has dual functions of carrier transport and carrier recombination, so as to simplify a cell structure and optimize the photoelectric conversion efficiency. The tandem cell and the manufacturing method thereof according to the present disclosure are used for manufacturing the tandem cell.
