· JVASP-38057· Rb2NaBiCl6

Rb2NaBiCl6 is a halide perovskite ceramic compound belonging to the double perovskite family, which combines alkali metals (rubidium and sodium) with bismuth and chlorine in a structured ionic lattice. This material is primarily investigated in research contexts for optoelectronic applications, particularly as a lead-free alternative in photovoltaic and scintillation detector systems where bismuth substitution offers reduced toxicity compared to conventional lead-based perovskites. Engineers consider halide perovskites like this for next-generation solar cells, X-ray detectors, and radiation sensing due to their tunable bandgap and ionic conductivity, though the material remains largely in the development phase with ongoing work to optimize stability and performance.
