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 MAPbI3. when used for solar cell.
