Abstract

Halide perovskites are promising photovoltaic materials owing to their high energy conversion efficiencies. Although significant progress has been made in their optoelectronic properties, their mechanical properties, which are critical for the stability and robustness in working conditions, are less reported. Here we employ nanoindentation methods to systematically study the elastic, plastic, fracture, and creep properties of various halide perovskites in their bulk single-crystal forms. We analyze in detail the potential factors influencing each of these properties. This work provides an investigation of the mechanical stability of halide perovskites and the relationships between their structures and mechanical properties, contributing to their advancement in practical applications.
