· K2 Ag2 Br6

K₂Ag₂Br₆ is a mixed-halide perovskite semiconductor compound containing potassium, silver, and bromine in a crystalline structure. This is a research-stage material being investigated for optoelectronic applications, particularly in the broader family of halide perovskites that show promise for photovoltaic and light-emission devices. Silver halide perovskites are of interest as potential alternatives to lead-based perovskites, offering potential advantages in toxicity reduction while maintaining semiconductor functionality, though they generally exhibit wider bandgaps and more limited performance maturity compared to established lead-halide systems.
