Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for preparing a trans-type three-dimensional perovskite solar cell based on a photonic crystal heterojunction. Background technique [0002] With the increasing global energy crisis, solar energy has become a research hotspot in the field of renewable clean energy due to its advantages of abundant resources, wide distribution, and environmental protection. Perovskite solar cells (PSCs) have the characteristics of high photoelectric conversion efficiency, low cost, and simple process. As one of the most promising photovoltaic power generation technologies, they have received extensive attention. [0003] Generally, PSCs have three typical structures, which are formal mesoporous structure (conducting glass (FTO) / electron transport layer / mesoporous layer / perovskite light absorption layer / hole transport layer / metal electrode), formal planar structure ( FTO / electron tran...
