Control of the quality and homogeneity of halide perovskites by mixed-chloride additives upon the film formation process
Daming Zheng, Thierry Pauporté
Abstract
The roles of mixed ammonium chloride and potassium chloride additives on the growth of Cs 0.1 FA 0.9 PbI 3 perovskite film are investigated along with the surface treatment by an n -propylammonium iodide solution which produces an interfacial buffer layer.
