Abstract All-polymer solar cells (all-PSCs) have attracted significant research attention in recent years, primarily due to their advantages of outstanding photo-thermal stability and excellent mechanical flexibility. However, all-PSCs typically exhibit complex morphologies during the film formation blend films, tendency become entangled polymer chains, negatively impacting fill factor (FF) morphology stability. Therefore, optimization co-mingled heterojunction is crucial for improving device performance. Recent studies reveal that solid additives (SAs) can realize regulation molecular aggregation state, packing, domain size active layer, which not only improves exciton dissociation, charge transport collection process but also ultimately realizes enhancement efficiency. this review provides an in-depth insight into different mechanisms all-PSCs, offering a comprehensive discussion on progress optimizing enhancing Finally, we present outlook further structural modification strategies towards better bulk paving way achieving stability, superior flexibility, high-efficiency all-PSCs.

Abstract A novel A‐D‐A type small molecule (DTP‐2EH‐IO2Cl) incorporating dithiophenepyrrole (DTP) core with indene‐dione (IO2Cl) side chain an intermediate band gap and rigid structure is incorporated into polymer donor PM6 one of the three A−DA′D−A acceptor—L8‐BO, BTP‐eC9 or Y6—for ternary‐blend organic photovoltaics (OPVs). The third component DTP‐2EH‐IO2Cl induces not only energy transfer but also stronger molecular packing acceptors, resulting in a larger coherence length enhanced absorption that enhances devices’ power conversion efficiencies (PCE) thermal stability. PCE values champion devices PM6:L8‐BO, PM6:BTP‐eC9, PM6:Y6 are 19.2, 18.3, 17.6%, respectively, versus 16.5, 15.8, 15.4% for their corresponding binary blend devices, displaying relative increases from 14 to 16%. stability (T 80 ) PM6:L8‐BO: ternary device dramatically 568 h 57 PM6:L8‐BO device. These enhancements can be attributed effectiveness as increasing light through inducing intermolecular providing effective way tune morphology boost both OPVs.
