High Purity n-Butylammonium Iodide (BAI, C4H12IN), 99.5%, 5g

n-Butylammonium Iodide (BAI) is a popular additive in organic–inorganic halide perovskite materials (ABX3), such as MAPbI3, to improve the stability of perovskite by tuning the morphology of the perovskite crystals. BAI has longer organic chain compare to methylammonium iodide (MAI). Its organic chain acts as a spacer between crystal phases thus reducing the 3D perovskite crystals into 2D plate-like crystals, reducing the band gap of the perovskite and increasing their stability to heat, irradiation and moisture.
