CAS 14965-49-2: Methanamine, hydriodide

Methylamine hydroiodide is a chemical compound that has been used as a light-sensitive absorber in solar cells. It can be synthesized by reacting methylammonium with hydroiodic acid, although it can also be prepared electrochemically. Methylamine hydroiodide is crystalline and has an optical band gap of 1.2 eV, which makes it an efficient absorber of electromagnetic radiation in the visible region of the spectrum. The hydrogen bond between the methylammonium and iodide groups provides for its stability and high chemical reactivity. The functional groups on methylamine hydroiodide have been studied using various techniques, including electrochemical impedance spectroscopy (EIS), thermal analysis, and crystallography.
