Abstract Ternary strategyopens a simple avenue to improve the power conversion efficiency (PCE) of organic solar cells (OSCs). The introduction wide bandgap polymer donors (PDs) as third component canbetter utilize sunlight and mechanical thermal stability active layer. However, efficient ternary OSCs (TOSCs) with two PDs are rarely reported due inferior compatibility shortage match acceptors. Herein, PDs‐(PBB‐F PBB‐Cl) adopted in dual‐PDs systems explore underlying mechanisms their photovoltaic performance. findings demonstrate that components exhibit excellent miscibility PM6 embedded host donor form alloy‐like phase. A more profound mechanism for enhancing through dual mechanisms, guest energy transfer charge transport at donor/acceptor interface, has been proposed. Consequently, PM6:PBB‐Cl:BTP‐eC9 TOSCs achieve PCE over 19%. Furthermore, better than binary reduction spatial site resistance resulting from tightly entangled long‐chain structure. This work not only provides an effective approach fabricate high‐performance TOSCs, but also demonstrates importance developing compatible PD materials.

Abstract Trap-assisted charge recombination is one of the primary limitations restricting performance organic solar cells. However, effectively reducing presence traps in photoactive layer remains challenging. Herein, wide bandgap polymer donor PTzBI-dF demonstrated as an effective modulator for enhancing crystallinity bulk heterojunction active layers composed D18 derivatives blended with Y6, leading to dense and ordered molecular packings, thus, improves photoluminescence quenching properties. As a result, photovoltaic devices exhibit reduced trap-assisted losses, achieving optimized power conversion efficiency over 19%. Besides enhancement, comprised third component simultaneously attain decreased current leakage, improved carrier mobilities, suppressed bimolecular recombination, energy losses. The advanced crystalline structures induced by its characteristics, such well-aligned level, complementary absorption spectra, are ascribed promising improvements. Our findings suggest that phase engineering feasible approach tuning packings layer, providing guidelines designing morphology modulators high-performance

Abstract All‐polymer systems are promising for commercial applications because the lower diffusivity of polymers helps to inhibit large‐scaled phase separation and obtain excellent stability. Achieving a fine‐tuned morphology active layer with an appropriate vertical has long been major goal in obtaining efficient all‐polymer solar cells (all‐PSCs). Herein, through synergistic effect layer‐by‐layer (LBL) structure dual donor strategy, high performance stable all‐PSCs prepared by constructing interpenetrating network. The introduction third component PTzBI‐dF suppresses excessive aggregation reduces exciton recombination. formation favorable p‐i‐n adjust distribution improve Ultimately, fine optimization, PBQx‐T‐Cl:PTzBI‐dF/PY‐IT achieves PCE 18.83%. This research demonstrates simple effective way construct high‐performance OSCs desirable distribution.
