Abstract Using two structurally similar polymer acceptors in constructing high‐efficiency ternary all‐polymer solar cells is a widely acknowledged strategy; however, the focus thus far has not been on how acceptor(s) would tune aggregation of donors, and furthermore film morphology device performance (efficiency stability). Herein, it reported that matching celebrity acceptor PY‐IT donor PBQx‐TCl results enhanced H ‐ PBQx‐TCl, which can be finely tuned by controlling amount second PY‐IV. Consequently, efficiency‐optimized PY‐IV weight ratio (0.2/1.2) leads to state‐of‐the‐art power conversion efficiency 18.81%, wherein light‐illuminated operational stability also along with well‐protected thermal stability. Such enhancements stabilities attributed optimization desired glass transition temperature target active layer based comprehensive characterization. In addition being high‐power case for cells, these are successful attempt using combined toward optimal morphology, provides theoretical basis construction other types organic photovoltaics beyond cells.
