· JVASP-109894· KRb2AsI6

KRb2AsI6 is an inorganic halide perovskite ceramic composed of potassium, rubidium, arsenic, and iodine. This is an experimental research compound investigated for its potential in optoelectronic and photovoltaic applications, particularly as an alternative perovskite absorber material where the double-halide structure may offer improved stability or tunable electronic properties compared to conventional lead-halide perovskites. Engineers and researchers evaluate such mixed-cation halide perovskites for their ability to balance light absorption, charge transport, and material durability in next-generation solar cells and radiation detection systems.
