In perovskite solar cells (PSCs), the selection of hole‐transport material (HTM) markedly influences both achievement high efficiency and overall stability. This study outlines synthesis a dopant‐free HTM founded on donor–acceptor 1 –acceptor 2 (D–A –A )‐conjugated structure its integration into PSCs. The ensuing PSCs showcase power conversion 17.8%, comparable to NiO x inorganic HTM‐based devices surpassing poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate polymeric devices. is attributed efficient hole extraction transport facilitated by conjugated π junctions in specifically designed structure. Furthermore, these exhibit enhanced stability, maintaining 95% their initial performance for 60 d an N atmosphere without encapsulation. improved stability primarily arises from hydrophobic nature HTM. larger π‐conjugated molecules lead denser film reducing intermolecular space, effectively retarding water intrusion providing superior protection layer. Thus, D–A with extended not only enhances device but also substantially improves
