SnIBr

SnIBr is a mixed-halide perovskite ceramic compound containing tin, iodine, and bromine. This material is primarily investigated in materials science research as a lead-free alternative for optoelectronic applications, particularly in photovoltaic and light-emission contexts where the perovskite crystal structure enables favorable electronic properties. The tin-halide family offers potential advantages over lead-based perovskites in terms of environmental safety and regulatory compliance, though tin-halide perovskites remain largely in the research and development phase with ongoing work to improve stability and defect tolerance compared to established alternatives.
