Rb2CuSbBr6

Rb2CuSbBr6 is a halide perovskite compound containing rubidium, copper, antimony, and bromine, representing an emerging class of metal halide materials under active research for optoelectronic and photovoltaic applications. This double-perovskite structure is being investigated as a lead-free alternative to conventional perovskites, with potential use in solar cells, light-emitting devices, and radiation detectors where reduced toxicity and improved stability are priorities. The material remains largely in the experimental phase; engineers and researchers select such compounds to develop next-generation devices that combine improved environmental compatibility with competitive performance characteristics.
