Abstract

In recent years, lead-based perovskites have become the most promising photovoltaic material showing excellent photovoltaic performances. However, the lead-based perovskite encounters instability and toxicity issues caused by the generation of Pb²⁺, which is highly not beneficial to environment. In this study, we firstly reported the synthesis and characterization of a novel lead-free mixed chalcogen-halogen perovskite material, MABiI₂S (MBIS), and determined its physical and optical properties by various testing methods. The MBIS possesses a low bandgap of 1.52 eV and exhibits good absorptions across the visible light spectrum. It is also worth noting that the MBIS displayed absorption up to over 1000 nm.
