· RbNb4Br11

RbNb4Br11 is a mixed-halide layered perovskite semiconductor composed of rubidium, niobium, and bromine. This is a research-stage compound under investigation for optoelectronic and photovoltaic applications, where the layered perovskite family has shown promise for tunable bandgaps, improved stability, and solution-processable synthesis compared to conventional perovskites. The specific rubidium-niobium composition offers potential for engineering band structure and charge transport properties in thin-film devices, though industrial deployment remains limited pending further characterization and scale-up viability.
