A multi‐dimensional synergistic strategy incorporating polymer acceptor PYF‑T‑ o into sequentially deposited PM6/eC9 was developed. This approach broadens spectral absorption, refines phase separation, and reduces energetic disorder to 23.43 meV, yielding 20.23% efficiency with a T80 lifetime of 260 h. This work provides a robust paradigm for synchronously reducing non‑radiative loss and enhancing organic solar cell performance. More details are discussed in the article by Zeng et al . on pages 3131—3138. image
