· Y1 Se1 Cl1

YSeCI is a mixed-halide selenide compound combining yttrium, selenium, and chlorine in a 1:1:1 stoichiometry. This is a research-phase semiconductor material, part of the broader family of metal chalcogenide halides that have attracted recent attention for potential optoelectronic and photovoltaic applications. YSeCI and related compounds remain largely in the experimental stage, with limited industrial deployment; the material is of primary interest to researchers exploring next-generation semiconductors that may offer tunable bandgaps, improved thermal stability, or reduced toxicity compared to conventional lead-halide perovskites.
