Roles that Organic Ammoniums Play on the Surface of the Perovskite Film: A Review
Xiaotao Liu, Yu Qiao, Xin Guo
Abstract
The roles of organic ammonium salts (OASs) which are widely used for the surface treatment of the perovskite film, including formation of 2D perovskites, direct surface passiviation, and other effects, have been reviewed. The influencing factors for these roles of OASs are also discussed, which are important for improved efficiency and stability of perovskite solar cells. More information can be found in the Review article by X. Guo and co-workers. (DOI: 10.1002/chem.202203001).
