· JVASP-109254· K2RbTaI6

K2RbTaI6 is a halide perovskite ceramic compound containing potassium, rubidium, tantalum, and iodine. This is a research-stage material being investigated for optoelectronic and photovoltaic applications, particularly as part of the broader exploration of mixed-cation halide perovskites for next-generation solar cells and light-emitting devices. The incorporation of multiple alkali cations and the heavy metal tantalum suggests investigation into stability enhancement and bandgap engineering compared to simpler lead halide perovskites.

Regulatory Screening

Environmental

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.
