Abstract

The invention relates to a perovskite solar cell and a preparation method thereof, comprising: a transparent conductive substrate, a hole transport layer formed sequentially on the transparent conductive substrate, a perovskite light absorbing layer, and a hydrophobic long-chain high Molecular layer, an electron transport layer composed of zinc oxide nanocrystals filled in the mesh of the hydrophobic long-chain polymer layer, and a back electrode, wherein the hydrophobic long-chain polymer layer is polytetrafluoroethylene, trifluoro At least one of ethylene and vinylidene fluoride. The present invention proposes for the first time that hydrophobic long-chain polymers are introduced into the preparation of perovskite solar cells as hydrophobic materials to improve the stability of perovskite solar cells.

Description

technical field [0001] The invention belongs to the field of inorganic nanometer materials, in particular to a long-term stable perovskite solar cell, 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 solar cells, comparable to T...
