· CrBi2I2O11

CrBi2I2O11 is a mixed-valent chromium bismuth iodide oxide compound belonging to the family of layered perovskite-related semiconductors. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications, where the combination of chromium and bismuth cations offers potential for tunable bandgap and enhanced light absorption compared to conventional halide perovskites. It represents an emerging class of lead-free halide semiconductors being explored as an alternative to organic-inorganic perovskites, with particular interest in photovoltaic devices, photodetectors, and scintillation applications where stability and non-toxicity are design drivers.
