High Purity Dimethylammonium Bromide (DMABr, C₂H₈BrN), 99.5%, 3g

Dimethylammonium Bromide (DMABr) is a popular additive in Bromide based perovskite materials (ABX₃), such as CsPbBr_3, to improve the stability of perovskite by tuning the morphology and crystallization of the perovskite crystals. It is also a precursor of didodecyl dimethyl ammonium bromide (DDAB), which is another additive of perovskite solar cells that provides a hydrophobic layer on top of the perovskite layer, which reduces the direct contact between the perovskite and moisture to improve the moisture resistance.
