Formamidinium iodide

Description

Formamidinium lead iodide shows a narrower bandgap than the commonly used methylammonium lead?iodide (1.48 eV compared to ~1.57 eV),?and hence lies closer to that favourable for optimum solar conversion efficiencies. With an approach of FAPbI3 crystallisation by the direct intramolecular?exchange of dimethylsulfoxide (DMSO) molecules intercalated in PbI2 with formamidinium?iodide, device with performance over 20% has been fabricated.

What are the applications of Application

The Uses of Formamidinium iodide

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.

The Uses of Formamidinium iodide

Formamidinium iodide (FAI) is an organic halide, which can be used as a precursor solution in the fabrication of perovskite-based heterojunction solar cells.
