Herein, two small-molecule acceptors Y6 and Y6-1O with similar chemical structures were combined with polymer donor D18 to fabricate as-cast OSCs. The two highly compatible acceptors possess complementary bandgaps and energy levels, which contribute to achieving an optimal balance between the short-circuit current density and open-circuit voltage in ternary OSCs by modulating the Y6/Y6-1O ratio. Moreover, film-formation dynamics, morphological, and theoretical explorations reveal that the easily clustered Y6-1O shows a larger binding energy with D18 than that of the group of Y6 and D18, leading to a faster film-formation process of the active layer. Manipulating the Y6-1O content in the ternary matrix can effectively control the aggregation of D18 by shortening the film-formation time, and then forming profitable film morphology for efficient exciton dissociation, charge transport, and collection, thus reducing the energy loss and improving the fill factor of the device. Consequently, the synergistic effect of two acceptors results in the as-cast ternary device achieving a top-ranked power conversion efficiency (PCE) of 19.51%. This work demonstrates an effective approach with the ternary strategy to construct high-performance as-cast devices.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although progress has been made, persistent limitations in data processing, modeling, and scenario evaluation continue to hinder further advances. Artificial Intelligence (AI) is emerging as a powerful tool to address these challenges by integrating diverse data sources, enhancing predictive modeling, and supporting evidence-based decision-making. Its capacity to manage large datasets and facilitate knowledge sharing has already made meaningful contributions to climate research and action. This paper introduces the RACC theoretical framework, developed through a systematic integration of the research paradigms of the three IPCC Working Groups (WGI, WGII, and WGIII). The RACC framework provides a comprehensive structure encompassing four key stages: data collection, scenario simulation, pathway planning, and action implementation. It also proposes a standardized approach for embedding AI across the climate governance cycle, including areas such as climate modeling, scenario development, policy design, and action execution. Additionally, the paper identifies major challenges in applying AI to climate issues, including ethical concerns, environmental costs, and uncertainties in complex systems. By analyzing AI-supported pathways for mitigation and adaptation, the study reveals significant gaps between current practices and long-term objectives-especially regarding content, intelligence levels, and governance structures. Finally, it proposes strategic priorities to help realize AI's full potential in advancing global climate action.","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":18.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
