Application

Formamidinium iodide (FAI) is a compound that finds significant application in the field of photovoltaics, particularly in the development of perovskite solar cells. Formamidinium-based perovskite materials derived from FAI have also shown potential in other optoelectronic applications. These include light-emitting diodes (LEDs), photodetectors and lasers.
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors with extremely low water contents are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.
