The widely used one‐step spin‐coating method for perovskites suffers due to the narrow processing window of antisolvents. In article number 1901162, Shuyu Zhang and co‐workers demonstrate a solution; incorporating Nd3 + into MAPbBr3 perovskites. The Nd3 + incorporation leads to a significantly broadened processing window for antisolvent dripping. The films exhibit high stability with enhanced PLQY and phase purity due to induced heterogeneous nucleation.
