· Rb2 Pb2 Br6

Rb₂Pb₂Br₆ is a halide perovskite semiconductor compound composed of rubidium, lead, and bromine. This material belongs to the emerging class of metal halide perovskites, which are being actively researched for optoelectronic and photovoltaic applications due to their tunable bandgap, solution processability, and strong light-absorption characteristics. While not yet in widespread commercial production, rubidium lead bromide perovskites are of particular interest as stable alternatives to more commonly studied methylammonium and cesium-based perovskites, with potential advantages in thermal stability and long-term device performance.
