· K1 Au1 I4 O12

K1Au1I4O12 is an iodide-based semiconductor compound containing potassium, gold, and iodine with oxygen in the lattice structure. This is a research-stage material from the halide perovskite and mixed-metal iodide families, studied primarily for optoelectronic and photovoltaic applications where gold doping or incorporation offers potential advantages in charge transport or light absorption. While not yet in mainstream industrial production, compounds in this family are of interest to researchers exploring next-generation solar cells, photodetectors, and light-emitting devices, where alternative absorber materials with tunable bandgaps and improved stability are needed.
