Application

Formamidinium bromide is commonly used as a precursor for the fabrication of perovskite absorber layers in perovskite solar cells. It can be combined with other components, such as lead halides and organic cations, to form the perovskite structure. FABr helps improve the optoelectronic properties and stability of the perovskite layer.
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.
