Controllable Perovskite Crystallization by Water Additive

In this work, we report a simple and effective method to control the growth of crystalline perovskite films by using water as a solvent additive for perovskite solution precursor. Incorporating of suitable amount of deionized water into the anhydrous DMF based perovskite precursor solutions can improve the crystallization of perovskite thin
