· Ba1 Ca1 I4

BaCaI₄ is a mixed halide perovskite semiconductor compound containing barium, calcium, and iodine. This material is primarily of research interest for optoelectronic and photovoltaic applications, representing an emerging class of lead-free halide perovskites being explored as alternatives to conventional perovskite absorbers. The incorporation of multiple metal cations (barium and calcium) into the perovskite structure offers potential for tuning electronic bandgap, thermal stability, and environmental durability compared to single-cation systems.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
