High Purity Ethylammonium Bromide (EABr, C2H8BrN), 99.5%, 5g

Ethylammonium Bromide (EABr) is a popular additive in perovskite materials (ABX3), such as MAPbBr3, to improve the stability of perovskite by tuning the morphology of the perovskite crystals. EABr additive helps to retard the crystal growth of perovskite films to produce a highly crystalline perovskite film with micronized grains and with reduced grain boundaries, thus improve the efficiency, long-term stability.
