High Purity Formamidinium Bromide (FABr, CH₅BrN₂), 99.5%, 10g

Formamidinium Bromide (FABr) is one of the main precursors of FAPbBr₃ organic–inorganic halide perovskite materials (ABX₃). The organic–inorganic halide perovskite solar cells have attracted tremendous attention worldwide and made great strides over the past few years with an inspiring efficiency up to 25.2%, rapidly approaching its theoretical value of 31%. Comparing to MAPbI₃, which is the most widely studied organic–inorganic halide perovskite materials, bromide-based perovskites have been shown to be stable against humidity and O₂ in the ambient air while FA make the solar cell more stable at elevated temperature. Thus FAPbBr₃ shows better stability than MAPbI_3. when used for solar cell.
