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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

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.

Solid-state light-emitting devices based on direct-bandgap semiconductors have, over the past two decades, been utilized as energy-efficient sources of lighting. However, fabrication of these devices typically relies on expensive high-temperature and high-vacuum processes, rendering them uneconomical for use in large-area
