Abstract

A tandem cell is provided in the present disclosure, which relates to the technical field of photovoltaics, so as to form a functional layer with high film ordering on a bottom cell, thereby improving photoelectric conversion efficiency of the tandem cell. The tandem cell includes: a bottom cell with a textured surface; a hole transport layer formed on the textured surface of the bottom cell; a second ordered induction layer and a perovskite absorption layer formed on the hole transport layer, the second ordered induction layer being located between the hole transport layer and the perovskite absorption layer; and a transparent conductive layer formed on the perovskite absorption layer. An inducing material contained in the second ordered induction layer is organic ammonium salt or inorganic lead compound. The tandem cell according to the present disclosure is a tandem cell with a perovskite solar cell as a top cell.
