· JVASP-12538· InPb2I5

InPb2I5 is a mixed-metal halide ceramic compound combining indium and lead iodides, belonging to the perovskite-related family of materials. This is primarily a research-phase material investigated for optoelectronic and photovoltaic applications, particularly in next-generation solar cells and radiation detection devices where the combination of heavy metal elements provides strong photon absorption and charge carrier transport. The material's potential advantages over single-cation halide perovskites include tunable bandgap, improved stability, and enhanced radiation stopping power—making it of interest to researchers developing lead-halide alternatives for energy conversion and sensing, though commercial deployment remains limited.
