Formamidinium Bromide (FABr), >=99.5%

Cat No:BMSPEM-0106

Description

Formamidinium bromide (FABr) is the hydrobromide of formamidine and the bromide analogue of the formamidinium cation family that underpins FA-based halide perovskites. Blending FABr with iodide and cesium sources lets researchers tune the bandgap, carrier diffusion length and power conversion efficiency of perovskite absorbers, and the small, symmetrical cation also stabilises the photoactive black phase. The salt is delivered at >=99.5% purity after four purification passes, melts at 135 C, and is packed under argon with protection from light because it picks up moisture readily.
