· JVASP-102873· K2AlInBr6

K2AlInBr6 is a halide perovskite compound combining potassium, aluminum, indium, and bromine—a member of the emerging double-perovskite family. This is primarily a research material being investigated for optoelectronic and photovoltaic applications, particularly as an alternative to lead-based perovskites due to its potential for lower toxicity and greater environmental stability while maintaining semiconducting properties.
