Abstract The morphology of the photoactive layer plays an important role in both photoelectric effect and device performance solution‐processed organic solar cells (OSCs). Optimizing requires precise control over complex film formation kinetics, which are influenced by a range factors from solution state to solid‐film state. This review delves into situ characterization technologies employed understand active process explores strategies for controlling during key stages, including aggregation, nucleation, crystal growth, phase separation. Special attention is given mechanism these enable real‐time printing their potential facilitate direct layers with optimized morphology. goal offer valuable insights guidance managing kinetics OSCs, ultimately addressing challenges scale‐up paving way high‐throughput production post‐processing‐free devices.

Abstract Disordered polymer chain entanglements within all‐polymer blends limit the formation of optimal donor–acceptor phase separation, and thus performance organic solar cells (all‐PSCs). Considering challenge importance morphology regulation in all‐PSCs, a diluted layer‐by‐layer (N‐LBL) strategy is thereby adopted to fine‐tuning properties blends. When comparing traditional PM6:PY‐IT based bulk‐heterojunction (BHJ) film PM6/PY‐IT (LBL) film, N‐LBL which prepared from PM6 (with 3% PY‐IT) bottom layer PY‐IT 6% PM6) top layer, displayed clearer bi‐continuous fibrillar network higher exciton generation process. Benefiting these unique characters, all‐PSC consisting active exhibited short‐circuit current density over 26 mA cm −2 power conversion efficiency (PCE) 18.33%, are both than those BHJ (16.88%) LBL (17.13%) devices. Moreover, universality dilution other (PM6 PY‐DT, PY‐FT‐ o ) also demonstrated with unanimously improved device performance. This work underscores effectiveness method tuning morphologies charge dynamics for high‐performance all‐PSCs.

Abstract Disordered polymer chain entanglements within all‐polymer blends limit the formation of optimal donor‐acceptor phase separation. Therefore, developing effective methods to regulate morphology evolution is crucial for achieving morphological features in organic solar cells (APSCs). In this study, two isomers, 4,5‐difluorobenzo‐ c ‐1,2,5‐thiadiazole (SF‐1) and 5,6‐difluorobenzo‐ (SF‐2), were designed as solid additives based on widely‐used electron‐deficient benzothiadiazole unit nonfullerene acceptors. The incorporation SF‐1 or SF‐2 into PM6 : PY‐DT blend induces stronger molecular packing via interaction, leading continuous interpenetrated networks with suitable phase‐separation vertical distribution. Furthermore, after treatment SF‐2, exciton diffusion lengths films are extended over 40 nm, favoring charge transport. asymmetrical characterized by an enhanced dipole moment, increases power conversion efficiency (PCE) PY‐DT‐based device 18.83 % due electrostatic interactions. Moreover, a ternary strategy boosts PCE SF‐2‐treated APSC 19 %. This work not only demonstrates one best performances APSCs but also offers approach manipulate using rational‐designed additives.

Morphology optimization of blend films is an essential strategy to enhance the photovoltaic performance organic solar cells (OSCs). Additive engineering effective for fine-tuning active layer morphology. Given limited efforts and achievements in designing synthesizing liquid additives, new solid additives manipulate morphology layers have gained widespread attention. Herein, 1,4-dimethoxynaphthalene (DMNA), with merits simple structure, low cost, ecofriendliness, successfully incorporated as a novel additive optimize OSCs based on D18-Cl:N3. The relationship between different DMNA contents device has been investigated. It found that can be effectively regulated by DMNA, leading enhanced molecular packing films, which favors exciton dissociation, charge transfer, suppression recombination. As result, 18.61% power conversion efficiency (PCE) obtained D18-Cl:N3 binary devices better than 17.21% PCE control device. This primarily due simultaneous increase short-circuit current density fill factor. Furthermore, general applicability confirmed other systems. These results suggest presents potential prospects regulating bulk heterojunction toward high-performance high-stability OSCs.
