The impact of precursor water content on solution-processed organometal halide perovskite films and solar cells Universiteit Hasselt
Perovskite solar cells are well known to degrade under post-fabrication stress, among others due to humidity as a consequence of the hydrophilic properties of the organic cation. On the other hand, it has been shown that the controlled addition of water molecules during the formation of the perovskite (while starting from water-free precursor materials) yields larger perovskite crystals with less defects, resulting in better device performance. ...
