· Br6 Rb2 W1

Rb₂WBr₆ is an inorganic halide perovskite semiconductor composed of rubidium, tungsten, and bromine. This material belongs to the emerging class of lead-free perovskite compounds under active research for optoelectronic and photovoltaic applications, offering potential advantages in stability and toxicity compared to conventional lead-halide perovskites. While primarily in the research phase, it is investigated for next-generation solar cells, photodetectors, and light-emitting devices where the combination of mechanical rigidity and semiconductor behavior could enable efficient energy conversion in environmentally safer platforms.
