· Ba2 Ca4 I12

Ba₂Ca₄I₁₂ is a mixed halide perovskite semiconductor compound combining barium, calcium, and iodine in a layered crystal structure. This is a research-phase material being investigated for optoelectronic and photovoltaic applications, particularly as an alternative or complement to lead-based perovskites, with potential advantages in stability and reduced toxicity. Engineers evaluating this material should recognize it as part of the emerging halide perovskite family used to develop next-generation solar cells, light-emitting devices, and radiation detectors where tunable bandgap and solution processability are critical.
