Exploring the origin of polaron formation in halide perovskites

Halide perovskites are a class of materials with an underlying structure resembling that of mineral perovskites, but with X sites occupied by halide ions, while their A and B sites are occupied by cations. These materials have various advantageous properties that make them promising candidates for the development of photovoltaics (PVs), light-emitting diodes (LEDs) and other optoelectronic devices.
