· Sr2 O2 Br1 Cu1

Sr₂O₂Br₁Cu₁ is an experimental mixed-anion oxide-bromide copper compound belonging to the layered perovskite or Ruddlesden-Popper family of semiconductors. This material is primarily of research interest for exploring new copper-based semiconductors with tunable electronic properties through mixed anionic substitution, rather than an established industrial material. Potential applications under investigation include photovoltaic devices, photoelectrochemical water splitting, and optoelectronic components, where the combination of copper, oxygen, and bromide anions may enable bandgap engineering and charge transport properties distinct from conventional oxides or halide perovskites.
