High Purity Formamidinium Iodide (FAI, CH₅IN₂), 99.5%, 5g

Formamidinium Iodide (FAI, CH₅IN₂) is one of the main precursors of FAPbI₃ 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, FAPbI₃ reveals a considerable advantage due to better thermal stability, longer carrier diffusion length, and smaller bandgap, which enables near-infrared absorption.
