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.

Laboratory-scale all-polymer solar cells (all-PSCs) have exhibited remarkable power conversion efficiencies (PCEs) exceeding 19%. However, the utilization of hazardous solvents and nonvolatile liquid additives poses challenges for eco-friendly commercialization, resulting in trade-off between device efficiency operation stability. Herein, an innovative approach based on isomerized solid additive engineering is proposed, employing volatile dithienothiophene (DTT) isomers to modulate intermolecular interactions facilitate molecular stacking within photoactive layers. Through elucidating underlying principles DTT-induced polymer assembly level, a PCE 18.72% achieved devices processed with environmentally benign solvents, ranking it among highest record values all-PSCs. Significantly, such superiorities DTT-isomerized strategy afford excellent compatibility large-area blade-coating techniques, offering promising pathway industrial-scale manufacturing Moreover, these demonstrate enhanced thermal stability extrapolated T80 lifetime 14 000 h, further bolstering their potential sustainable technological advancement.

Abstract Morphological control of all‐polymer blends is quintessential yet challenging in fabricating high‐performance organic solar cells. Recently, solid additives (SAs) have been approved to be capable tuning the morphology polymer: small‐molecule improving performance and stability devices. Herein, three perhalogenated thiophenes, which are 3,4‐dibromo‐2,5‐diiodothiophene (SA‐T1), 2,5‐dibromo‐3,4‐diiodothiophene (SA‐T2), 2,3‐dibromo‐4,5‐diiodothiophene (SA‐T3), were adopted as SAs optimize cells (APSCs). For blend PM6 PY‐IT, benefitting from intermolecular interactions between thiophenes polymers, molecular packing properties could finely regulated after introducing these SAs. In situ UV/Vis measurement revealed that assist morphological character evolution blend, leading their optimal morphologies. Compared as‐cast device : all SA‐treated binary devices displayed enhanced power conversion efficiencies 17.4–18.3 % with obviously elevated short‐circuit current densities fill factors. To our knowledge, PCE 18.3 for SA‐T1‐treated ranks highest among APSCs date. Meanwhile, universality SA‐T1 other demonstrated unanimously improved performance. This work provide a new pathway realizing APSCs.
