Evaporation Kinetics Engineering Suppressed Bimolecular Recombination in All‐Polymer Solar Cells
ABSTRACT All‐polymer solar cells (all‐PSCs) combine the synthetic tunability of non‐fullerene acceptor systems with intrinsic mechanical and thermal robustness of polymer active layers, yet their performance remains limited by pronounced bimolecular recombination, leading to insufficient fill factors (FFs) compared to...
