Formamidinium bromide >99.99%


Formamidinium Bromide (FABr; CAS Number 146958-06-7) is a popular precursor salt used in the preparation of organometal halide perovskite-based solar cells (PSCs). High solar cell efficiencies have been realised with mixed perovskites where the bromides and the formamidinium cations subsitute iodides and the methylammonium cations (Jacobsson et al., 2016). Zhang et al. (2018) also showed that formamidinium lead trihalide (FAPbBr3) photodetector shows good responsivity, external quantum efficiency, and detectivity.

Greatcell Solar Materials’ Formamidinium Bromide consists of a white powder produced with a purity level > 99.99%. It exhibits a superior quality thanks to a reproducible production process and an extremely low moisture content. Greatcell Solar Materials can provide g to kg quantities.
