Abstract

The invention relates to a perovskite solar cell with thermochromism performance and preparation method thereof. The solar cell is obtained through the following operations: forming a rutile phase vanadium dioxide film on a non-conductive surface of a transparent conducting substrate, and orderly forming an electronic transmission layer, a perovskite absorbing layer, a hole transporting layer and a back electrode on a conducting surface on the transparent conducting substrate, wherein the thickness of the vanadium dioxide film is 500 nanometers to 100 microns. The perovskite solar cell with thermochromism performance prepared by the invention can effectively regulate the indoor temperature while realizing the photoelectric conversion, the resource and energy are saved, and the solar cell use ratio is improved.

Description

technical field [0001] The invention belongs to the field of inorganic nanometer materials, and in particular relates to a perovskite solar cell with thermochromic performance, its preparation method and application field. Background technique [0002] In recent years, under the background of gradually intensifying energy crisis and deepening environmental pollution, the global field of optoelectronic research has made great progress, and has become one of the most promising and strategic research hotspots in this century. In this field, due to low cost, simple process and excellent performance, perovskite solar cells have become a research hotspot in the field of optoelectronic devices. The solar conversion efficiency of the solar cell first proposed in 2009 was only 4%. After 7 years of development, the certified efficiency has now reached 22%, surpassing the current photoelectric conversion efficiency of amorphous silicon solar cells and copper indium gallium selenide sol...
