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 MAPbI_3, 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.
