Bi2 Br2 O2
semiconductor· Bi2 Br2 O2
Bi₂Br₂O₂ is an oxyhalide semiconductor compound combining bismuth, bromine, and oxygen. This is primarily a research material in the halide perovskite and related semiconductor families, being investigated for optoelectronic and photovoltaic applications due to bismuth's advantageous electronic properties and the tunable bandgap achievable through halide composition. While not yet established in high-volume industrial production, materials in this chemical family are of significant interest as lead-free alternatives for solar cells, photodetectors, and light-emitting devices, offering potential advantages in stability and environmental compatibility compared to traditional halide perovskites.
