Description

technical field

[0001] The invention belongs to the field of organic semiconductor functional materials, and relates to a hole-transporting material with indanodithiophene as the core, a synthesis method thereof, and an application in perovskite solar cells. Background technique

[0002] In the past ten years, organic-inorganic hybrid perovskite solar cells (Perovskite Solar Cells, PSCs) have attracted extensive attention from researchers due to their advantages of low cost, high efficiency, and simple preparation process, and have become a research field. One of the research hotspots.

[0003] At present, the photoelectric conversion efficiency of perovskite solar cells has rapidly increased from the initial 3% to 24.2%. High-efficiency perovskite solar cell devices require a good stack structure, which is mainly composed of perovskite absorption layer, hole transport layer, electron transport layer and electrodes. Under light, the perovskite absorption layer in the batte...
