Title:
PN HETEROJUNCTION ANTIMONY SELENIDE/PEROVSKITE SOLAR CELL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/115870
Kind Code:
A1
Abstract:
Provided in the present invention is a PN heterojunction antimony selenide/perovskite solar cell. The solar cell comprises a substrate, a metal back electrode, a P-type antimony selenide layer, an N-type perovskite absorption layer and a conductive electrode, which are sequentially arranged. Compared with the prior art, the present invention can not only broaden the utilization range of a solar spectrum but can also reduce the thermal relaxation loss of photon-generated carriers by means of forming a multi-junction solar cell by a plurality of light absorbers that have different band gaps, thereby improving the photoelectric conversion efficiency; in addition, the present invention reduces the process preparation steps and cost and also improves the battery stability by means of a PN heterojunction Sb2Se3/perovskite absorption layer, without an electron transport layer, a hole transport layer, etc.
