Abstract

A charge carrier in a lead halide perovskite lattice is protected as a large polaron responsible for the remarkable photophysical properties, irrespective of the cation type. All-inorganic-based APbX<sub>3</sub> perovskites may mitigate the stability problem for their applications in solar cells and other optoelectronics.
