Methylammonium bromide in an organic halide with a formula of CH₃NH₃Br. It is an ammonium salt composed of methylamine and hydrogen bromide. 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 bromide instead of, or as minor substituent to, the iodide provides the ability to tune the absorption, conductivity, and apparent bandgap.
