Cat No:BMSPEM-0017
Low-water-content formamidine hydroiodide is a precursor for organohalide perovskite research. It is used to prepare mixed-cation or mixed-anion perovskites for optimizing band gap, carrier-diffusion length, and power-conversion efficiency in perovskite solar cells. The material is soluble in water and dimethylformamide and is sensitive to air, moisture, and light.
