Abstract
In this research highlight, recent significant advances with hot‐assisted blade‐coating or air knife‐assisted blade‐coating of different perovskite compositions with bandgaps ranging from 1.3 eV to 1.9 eV (i.e. wide‐bandgap or small‐bandgap perovskites with mixed cations and anions, 2D/3D perovskites, Pb/Sn binary perovskites, and all‐inorganic perovskites) for single‐junction or tandem PSCs are discussed, with an emphasis on elucidating the distinct ink formulation engineering strategies, crystal growth mechanisms, crystallization kinetics, and optoelectronic properties of the different perovskite compositions.
