· O1 Br4 W1

O1 Br4 W1 is a mixed-halide perovskite semiconductor compound containing bromine and tungsten in its structure. This material belongs to the emerging family of halide perovskites, which are actively researched for next-generation optoelectronic and photovoltaic applications due to their tunable bandgap and solution-processability. The bromine-tungsten combination represents an experimental composition aimed at improving stability, electronic properties, or photon absorption characteristics compared to more common lead-based perovskites.
