Tin Halide Perovskite Polycrystalline Films Formed With Nonhazardous 2-Propanol Solvent
CHEMISTRY LETTERS（2021）
摘要
The use of safe and environmentally friendly materials is an important issue for industrial mass production processes. In this study, we demonstrate the deposition of tin halide perovskite films using environmentally benign 2-propanol as a solvent. Sequential deposition of 2-propanol solutions containing SnBr2 and CH3NH3I led to the formation of CH3NH3SnBr3-xIx, which exhibited good crystallinity and visible-light absorption.
