Cubic or not cubic? The short-range order of tin halide perovskites

14 March 2022, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

Tin halide perovskites have the potential to overcome the toxicity issues of lead-based systems for photovoltaic devices. Elucidation of local structural features in these systems is of fundamental relevance to better understand the optoelectronic properties. This has been realized in ASnX3 (A= MA, FA, and X= I, Br) by total scattering and X-ray pair distribution function analysis, showing a trend of increasing local distortion as a function of organic cation, halide and temperature.

Keywords
