· Rb2SnBr6

Rb2SnBr6 is a halide perovskite ceramic compound belonging to the family of metal halides with potential optoelectronic and photovoltaic applications. This is a research-phase material being investigated as an alternative to lead-based perovskites, offering improved environmental and toxicity profiles while maintaining semiconducting properties suitable for light absorption and charge transport. The rubidium-tin-bromine system is of particular interest in next-generation solar cells, scintillators, and radiation detection devices where non-toxic, stable inorganic perovskites are required.
