· JVASP-5518· P3Se4I

P3Se4I is a mixed-halide selenide ceramic compound that belongs to the family of layered chalcohalide materials. This is an experimental/research-phase compound of primary interest in solid-state physics and materials chemistry, where it is being studied for its potential in photovoltaic applications, ionic conductivity, and optoelectronic devices. The combination of selenium and iodine in its structure offers tunable electronic properties and potential for next-generation thin-film absorbers or ion-conducting electrolytes, though practical industrial deployment remains in early development stages.
