Methylammonium chloride

Methylammonium chloride in an organic halide with a formula of CH3NH3Cl. It is an ammonium salt composed of methylamine and hydrogen chloride. The primary application for the methylammonium halides is as a component of perovskite (structure) crystalline solar cells.[3] Methylammonium iodide is the most commonly used, whereas using the chloride instead of, or as minor substituent to, the iodide provides the ability to tune the absorption, conductivity, and apparent bandgap.[4]
