· Al2 Se2 Br14

Al2Se2Br14 is a mixed-halide aluminum selenide compound belonging to the family of layered halide semiconductors. This is a research-phase material rather than an established commercial product, investigated primarily for its potential in optoelectronic and photovoltaic applications due to the bandgap engineering enabled by halide substitution. The compound represents an emerging class of materials being explored for next-generation thin-film solar cells, light-emitting devices, and radiation detection systems, where the combination of selenium and bromine allows tuning of electronic properties relative to simpler binary semiconductors.
