· JVASP-32829· PbIBr

PbIBr is a lead halide perovskite ceramic compound combining lead iodide and bromide components. This material belongs to the halide perovskite family and is primarily investigated in optoelectronic research rather than established industrial production, with potential applications in next-generation photovoltaic and light-emitting devices. Engineers consider PbIBr variants when tuning bandgap energy or stability characteristics in perovskite solar cells and LEDs, where the bromide content can be adjusted to optimize optical and electronic properties compared to pure iodide or chloride perovskites.
