Diethylammonium Iodide (DAI; CAS Number: 19833-78-4) is a precursor in the synthesis of perovskite-based opto-electronic systems. Huang et al. (2019) incorporated Diethylammonium Iodide as an organic Spacer in the preparation of MAPbI3 perovskites, resulting in stable and efficient photovoltaic devices.
Borun New Material - ChemBorun's Diethylammonium Iodide is of the highest purity affording consistent results and superior performance.
