CsBi2
semiconductor· CsBi2
CsBi₂ is a bismuth-based intermetallic compound with cesium, belonging to the family of metal halide perovskite-like or related bismuth semiconductors. This is primarily a research material under investigation for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in perovskite solar cells and related light-absorbing layers. CsBi₂ and related cesium-bismuth compounds are notable for their potential to address toxicity concerns associated with lead-based perovskites while maintaining semiconducting behavior suitable for energy conversion, though commercialization remains limited and material stability and efficiency optimization are active areas of study.
