Abstract
Abstract The power conversion efficiencies (PCEs) of all‐printed organic solar cells (OSCs) remain inferior to those of spin‐coated devices, primarily due to morphological variations within the bulk heterojunction processed via diverse coating/printing techniques. Herein, cyclohexyl is introduced as outer side chains to formulate a non‐fullerene acceptor, BTP‐Cy, aimed at modulating the molecular aggregation in solution and subsequent film formation kinetics during printing. Investigations demonstrate that BTP‐Cy molecule with cyclohexyl side chains exhibits enhanced intermolecular π‐π stacking, optimal solution aggregation size, and favorable phase separation. Consequently, PB3:FTCC‐Br:BTP‐Cy‐based OSCs…
