tert-Butylammonium Bromide (tBABr, C4H12BrN), 99.5%, 5g

tert-Butylammonium Bromide (tBABr) is used as an additive for perovskite since it can provide the tert-butyl bulky group, which can promote material solubility and device stability by tuning the morphology of the perovskite films. Since the tert-butyl bulky group has larger radius, it can server as splitter, changing the perovskite crystal to 2D plates and thus changes the morphology. It is usually used for bromide-based perovskite to avoid introducing other halide ions or intentionally to introduce bromide for non-bromide-based perovskite. nBABr, iBABr and tBABr can all serve the purpose, but tBABr is the best at increasing the stability but sacrificing the most efficiency while nBABr sacrifices the least efficiency and is the worst at increasing stability (still can increase more than 20% life time though).
