Inverted perovskite solar cell based on self-assembled monolayer achieves 24.38% efficiency

Researchers in China have designed an inverted perovskite solar cell with a new strategy aimed to optimize the cell's bottom region. The proposed cell was treated with two molecules known as 2-mercaptoimidazole and 2-mercaptobenzimidazole and was based on a hole transport layer relying on a self-assembled monolayer. A group of scientists led by Jiaxing University in China has developed an inverted perovskite solar cell based on a hole transport layer (HTL) with a self-assembled monolayer (SAM). Inverted perovskite cells have a device structure known as "p-i-n", in which hole-selective contact ...
