Abstract High‐performance organic solar cells often rely on halogen‐containing solvents, which restrict the photovoltaic industry. Therefore, it is imperative to develop efficient materials compatible with halogen‐free solvents. Herein, a series of benzo[ ]phenazine (BP)‐core‐based small‐molecule acceptors (SMAs) achieved through an isomerization chlorination strategy presented, comprising unchlorinated NA1, 10‐chlorine substituted NA2, 8‐chlorine NA3, and 7‐chlorine NA4. Theoretical simulations highlight NA3's superior orbit overlap length tight molecular packing, attributed interactions between end group BP unit. Furthermore, NA3 demonstrates dense 3D network structures record electronic coupling 104.5 meV. These characteristics empower ortho‐xylene ( o ‐XY) processed PM6:NA3 device power conversion efficiency (PCE) 18.94%, surpassing PM6:NA1 (15.34%), PM6:NA2 (7.18%), PM6:NA4 (16.02%). Notably, significantly lower PCE in excessive self‐aggregation NA2 ‐XY. Importantly, incorporation D18‐Cl into binary blend enhances crystallographic ordering increases exciton diffusion donor phase, resulting ternary 19.75% (certified as 19.39%). findings underscore significance incorporating new electron‐deficient units design SMAs tailored for environmentally benign solvent processing OSCs.

Abstract High performance organic solar cells (OSCs) are usually realized by using post‐treatment and/or additive, which can induce the formation of metastable morphology, leading to unfavorable device stability. In terms industrial production, development high efficiency as‐cast OSCs is crucially important, but it remains a great challenge obtain appropriate active layer morphology and power conversion (PCE). Here, efficient constructed via introducing new polymer acceptor PY‐TPT with dielectric constant into D18:L8‐BO blend form double‐fibril network morphology. Besides, incorporation enables an enhanced lower exciton binding energy layer. Therefore, dissociation charge transport in D18:L8‐BO:PY‐TPT‐based device, affording record‐high PCE 18.60% excellent photostability absence post‐treatment. Moreover, green solvent‐processed devices, thick‐film (300 nm) module (16.60 cm 2 ) fabricated, show PCEs 17.45%, 17.54%, 13.84%, respectively.

The ground-state charge generation (GSCG) in photoactive layers determines whether the photogenerated carriers occupy deep trap energy levels, which, turn, affects device performance of organic solar cells (OSCs). In this work, charge-quadrupole electrostatic interactions are modulated to achieve GSCG through a molecular strategy introducing different numbers F atom substitutions on BTA3 side chain. results show that 8F substitution (BTA3-8F) and 16F (BTA3-16F) lead patterns highest occupied orbital (HOMO) lowest unoccupied (LUMO) level changes. perfluorination phenyl chain endows BTA3-16F with LUMO similar BTA3, ensuring high VOC. Besides, features large moment, promoting strong between neighboring molecules along π-π stacking direction, which then induces components. This efficient directly makes significant impact subsequent kinetics exciton dissociation, recombination, transport over longer time periods, as well nonradiative recombination larger spatial scales. Benefiting from favorable suitable arrangement, PTQ10/BTA3-16F achieves VOC 1.302 V PCE 11.14%, setting world record for OSCs greater than 1.3 V. addition, is an effective guest molecule improve ternary OSCs, PM6/L8-BO/BTA3-16F-based 19.82%. result emphasizes important role components OSC demonstrates modulation quadrupole moments means designing acceptors.
