· Rb1 Sn1 Br3

RbSnBr₃ is a halide perovskite semiconductor compound combining rubidium, tin, and bromine in a cubic crystal structure. This is a research-phase material being investigated for next-generation optoelectronic devices, particularly as an alternative to lead-based perovskites due to tin's lower toxicity and rubidium's potential to improve stability and electronic properties. The material family is of interest to the photovoltaic and light-emission communities where perovskite semiconductors show promise for efficient, solution-processable devices with tunable bandgaps.
