Description General description i-Butlyammonium iodide (iso-BAI) is an ammonium salt that facilitates the formation of highly stable perovskites with good performance. These perovskite materials act as moisture resistant light absorbers. The butylamine is used as a spacing ammonium cation that supports the insulation of 2D perovskites. Application Iso-BAI in combination with formamidinium iodide (FAI) forms a mixture of bulky organic ammonium iodide, which is used in the fabrication of perovskite based solar cells with a power conversion efficiency of > 21%. The iodide and bromide based alkylated halides find applications as precursors for fabrication of perovskites for photovoltaic applications.
