Polymers or polymeric materials are used as additives for promoting the nucleation and crystallization of perovskite films to increase crystal grain size. Due their high molecular weight, polymers remain within perovskite‐crystal boundaries (GBs), where they passivate trap sites. Furthermore, some function charge‐transport in interfacial layers effectively separate charge carriers reduce recombination. Certain hydrophobic protect against moisture, whereas elastic contribute mechanical...
