Formamidinium iodide >99.99%


Formamidinium Iodide (FAI; CAS # 879643-71-7) is a common perovskite precursor used in perovskite-based opto-electronic systems (Lin et al., 2021). Perovskites using Formamidinium Iodide in their formulations have shown higher environmental stability and have a lower bandgap than Methylammonium Iodide-based perovskites, hence closer to the optimal band gap for a single junction cell (Ansari et al., 2018).

Greatcell Solar Materials’ Formamidinium Iodide (FAI) consists of white crystals produced with an extremely low moisture content and a purity level > 99.99%.

Greatcell Solar Materials can provide g to kg quantities.
