Medium-bandgap acceptors have proven effective for improving device performance, but their development still requires effective molecular design strategies. Here, a Y-series medium-bandgap acceptor, X3, was developed through side-chain engineering without altering the conjugated backbone by replacing the outer alkyl side chain with a 2,4,6-triisopropylphenyl (Tip) substituent. Tip functioned as a conformationally locked steric unit rather than merely as a bulkier substituent, thereby more effectively suppressing excessive intermolecular aggregation while only modestly perturbing the intrinsic electronic structure. As a result, X3 exhibited an optical bandgap of 1.50 eV. Single-crystal analysis further showed that Tip participated in multiple weak intermolecular interactions, giving rise to diverse packing motifs that consisted of localized π–π contacts and non-stacking interactions. Binary devices based on D18-Cl:X3 delivered a high open-circuit voltage (VOC) of 1.026 V, while the D18-Cl:N3:X3 ternary device achieved a power conversion efficiency (PCE) of 20.10%. These results highlight conformationally locked steric regulation as an effective side-chain design mode for pushing a Y-series scaffold toward the medium-bandgap regime and provide structure–property insight into side-chain-engineered acceptors for OPVs.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 14","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as a core step in the interconnection structure, the P2 process remains challenged by thermal damage, process complexity, and high costs associated with traditional laser scribing techniques. This work introduces a novel strategy using a low-temperature-cured conductive silver adhesive (CSA) as a simultaneous etchant and conductor in P2 process for perovskite solar modules. During CSA curing, its amine-based hardener selectively removes the perovskite and hole-transport layer, while the silver filler forms series connection with the bottom FTO electrode. Optimized at 90 °C and a 0.08 cm line width, the CSA-etched mini-modules achieved a champion efficiency of 17.96%, rivaling laser-ablated devices (18.36%). Crucially, by avoiding thermal damage, CSA-etched devices exhibited better storage stability under unencapsulated ambient conditions (25 °C, 25% RH), retaining 89% of their initial performance after 30 days, compared with 72% for laser-etched devices. This low-temperature CSA etching strategy offers a feasible alternative to high-precision laser P2 scribing in perovskite solar modules, reducing reliance on ultrafast laser equipment while enabling simultaneous removal of perovskite functional layers and electrical interconnection, thereby potentially lowering manufacturing costs.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 14","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, electrostatic adsorption dedusting based on transparent electrodes has become a popular research topic in the PV field, and transparent conductive film (TCF) materials with self-cleaning properties have become the preferred solution for PV dust removal. This article presents a hybrid method combining electrostatic adsorption dedusting with superhydrophobic coating to prepare a hydrophobic multifunctional single-walled carbon nanotube-nanosilicon dioxide (SWCNT-SiO2) TCF. The results showed that the index KA is 0.90, the light transmittance is 91.44%, and the sheet resistance is 41.80 kΩ/sq when the sol mass fraction of SWCNTs-SiO2 TCFs is 10 wt%. After electrostatic adsorption dedusting tests based on these TCFs, most of the dust was removed, and the conversion efficiency of the PV panels increased to 95.13% of that in a clean state. Simultaneously, the water contact angle reaches a maximum of 150.11°, showing superhydrophobicity, and the self-cleaning rate reaches 93.05% under laboratory simulation conditions. This study is expected to support the optimization and innovation of PV panel dust removal methods and the further development of the PV industry.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 14","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, ZnO was passivated with C60 and phenyl-C61-butyric acid methyl ester (PCBM) as single or stacked double layers, deposited by solution processing (cylinder blade coating and spin coating) to enable module fabrication. All device variants achieved comparable initial efficiencies (13.7 ± 0.2%). Under UV aging, the double-layer structure ZnO/PCBM/C60 showed superior stability: PCBM modifies the ZnO surface and provides a solution-processable contact, while the low-solubility C60 upper layer preserves the fullerene-rich interface during active-layer deposition. After 500 h UV irradiation (50 W/m2, approximating the natural sunlight UV fraction), unpassivated, single-, and double-passivated devices retained PCEs of 3.3%, 5.7%, and 6.8% (retention ratios of 23%, 37%, and 44%, respectively). Combining double-layer passivation with a low-cost UV-protective film further suppressed module degradation: after 1000 h, efficiency declined only from 13% to 12% (92% retention).

The initial undoped ZnO film exhibits a polycrystalline structure with a pronounced (002) orientation and low optical absorptance. However, the electrical properties of the film are characterized by high resistivity and instability, primarily attributed to its porous morphology. These limitations can be addressed by incorporating aluminum-doped zinc oxide or indium tin oxide seed layers, resulting in enhanced and more stable electrical performance. To demonstrate its applicability, this study reports the first successful integration of PECVD-grown ZnO film as a front-contact layer in silicon heterojunction solar cells. The addition of seed layers boosts the solar cell efficiency by increasing the fill factor through reduced series resistance. Despite the challenges with the initial film quality and the need to further refine the PECVD conditions to optimize the device performance, this study offers valuable insights into the current limitations and future potential of PECVD for TCO development. This lays the foundation for improving the PECVD process to produce high-quality TCO, potentially establishing it as an alternative deposition method for next-generation photovoltaic technology.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 14","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.70431","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional bulk heterojunction OSCs are plagued by uncontrollable morphology, serious charge recombination, and insufficient exciton utilization. Layer-by-layer deposition enables the construction of quasibilayer OSCs with well-defined vertical phase separation and ordered charge-transport channels, which offers a promising route to overcome the above bottlenecks. This review first systematically elaborates the general fundamental mechanisms of exciton dissociation in OSCs, covering basic processes, charge–transfer states, and singlet–triplet interconversion dynamics, and then focuses on the regulation strategies for exciton dissociation in OSCs from four aspects: morphology engineering, energy-level alignment, electric-field/polarization effects, and spin-state regulation. Next, the synergistic effect of structural features and energy-level engineering on exciton dissociation in quasibilayer OSCs is highlighted to address current challenges in optimizing this process. Finally, future research directions for quasibilayer OSCs are proposed, including thick-film compatibility and scalable processing. This review provides a comprehensive understanding of exciton dissociation in quasibilayer OSCs and offers guidance for developing high-efficiency, stable, and industrializable OSCs.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 14","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this critical challenge, this study fabricates lead iodide (PbI2) thin films using the evaporation method and systematically reveals the mechanism by which morphology regulation of the precursor films influences the crystallization quality and optoelectronic properties of perovskite films. By employing the evaporation distance of PbI2 as the core regulation strategy, we optimize the deposition state of the precursor films, enabling precise control over the micro-morphology and significantly enhancing the light absorption capability and charge transport performance of the films, which provides a clear mechanistic basis for preparing high-quality perovskite films. On this basis, combined with a two-step solution-assisted vapor deposition method, this study successfully achieves efficient and controllable preparation of large-area perovskite films.
