However, most Cs2SnX6 and derivatives have low catalytic activity mainly due to their insufficient light utilization efficiency. Herein, a simple in situ method is introduced to sensitize Cs2PtSnCl6 with Eosin Y (EY), forming EY-Cs2PtSnCl6 for HER in aqueous solution. Various characterizations indicate that the EY is immobilized onto the Cs2PtSnCl6 during the synthesis process. The EY-Cs2PtSnCl6 displayed extended light absorption range and efficient charge transfer from EY to Cs2PtSnCl6. The resulting EY-Cs2PtSnCl6 material exhibits high HER rate of 17.6 mmol g−1 h−1, ≈1760 folds than that of the pristine Cs2PtSnCl6. This work demonstrates an effective method to construct dye-sensitized perovskites and highlights the importance of interaction between dye and perovskite. It provides useful guidance for the design of new perovskite-based photocatalysts and it will advance the development of perovskites for solar energy conversion into renewable fuels.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"40 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Defect tolerance is previously thought to be a static property, determined solely by the composition and manufacturing process. However, recent studies have shown that the defect tolerance of MHPs is dynamic and can vary over time. For example, the power conversion efficiency of MHPs-based solar cells has been found to improve significantly under continuous illumination. Although this is a unique self-optimization behavior of MHPs, it can seriously affect the stability of power output of MHPs-based solar cells in real-world operating conditions. In view of this, extensive research has been conducted, but the physical mechanism of this photoinduced dynamic defect tolerance (DDT) has remained inconclusive, as both the mechanisms and experimental phenomena continue to be subjects of controversy. Therefore, a timely summarization on mechanisms related to DDT is urgently needed. In this review, a systematic overview is first provided of the experimental phenomena, characteristics, and influencing factors of the DDT. Following that, the proposed mechanisms for DDT are summarized, with a focus on carrier-defect and carrier-lattice interactions. Finally, the current challenges faced in DDT research are summarized and an outlook on the future developments is provided. This review aims to offer a comprehensive understanding of DDT in MHPs to enhance the performance and stability of MHPs-based solar cells, thereby facilitating the advancement and commercialization of these technologies.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"38 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the uncontrolled distribution of the third component in bulk heterojunction (BHJ) device often results in low energy transfer efficiency (EFRET), and also tends to compromise the interpenetrating network structure of active layer. Herein, a localized deposition strategy is proposed and establish a bulk heterojunction with a controlled distribution of the third component (CDBHJ). Take PM6:Y6:IBC-F for example, IBC-F serves as the energy donor and PM6 as the energy acceptor. Compared with BHJ-based devices, the proportion of IBC-F within the PM6 phase increases from 25.1% to 72.7%, enhancing EFRET from 46.5% to 66.8% in CDBHJ-based devices. Furthermore, the localized deposition strategy improves crystallization and phase separation kinetics during film-forming process. Thus, the CDBHJ-based device exhibits superior exciton generation, diffusion, and dissociation process, along with higher and more balanced charge transport. Consequently, the CDBHJ-based device achieves PCE of 18.29%, which ranks among the best for PM6:Y6-based T-OSCs. This work demonstrates the effectiveness of the localized deposition strategy in controlling the distribution of the third component, presenting an innovative pathway for the development of highly efficient T-OSCs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"7 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The routine oxygen-oxidation doping strategy falls short in achieving high-level doping due to the sparsity and random distribution of dopants within the solid Spiro-OMeTAD film.

However, the majority of diluents in LHCE systems consist of fluorinated ethers, which are not only dense and expensive but also demonstrate poor reductive stability with sodium metal. Herein, a low-density, non-fluorinated ether electrolyte is presented that demonstrates localized high-concentration behavior. This feature is driven by the weak solvating capabilities of 1,2-dimethoxypropane (DMP) and the ultra-weak solvating nature of cyclopentyl methyl ether (CPME). Impressively, the fluorine-free CPME cosolvent acts as a diluent within the electrolyte. Therefore, the electrolyte achieves a tailored solvation structure characterized by anion-rich species, which fosters the development of a resilient inorganic-rich SEI with superior Na-ion transport. Consequently, with a high sulfur-content sulfurized polyacrylonitrile (SPAN, S content > 45% in SPAN) loading of 4.4 mg cm⁻2 (sulfur loading: 2 mg cm⁻2) and a low electrolyte-to-SPAN ratio of 9 µL mg⁻¹ (E/SPAN = 9), the Na-SPAN cell demonstrates remarkable reversibility of 530 mA h gsulfur⁻¹ after 200 cycles at C/5 rate. This performance surpasses the majority of state-of-the-art Na-SPAN ether-based electrolyte systems reported to date. Hence, this work presents a novel approach for designing cost-effective, high-performance electrolytes for stable, practical Na-SPAN batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"130 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rechargeable zinc-air batteries (ZABs) have emerged as promising candidates that offer advantages such as high energy density, low cost, safety, and environmental friendliness. However, achieving high power density and cycling stability with low catalysts in ZABs at low temperatures remains a challenge. Herein, this study proposes the critical role of air pockets at the electrolyte-cathode interface to amplify the triple-phase boundary (TPB) and enhance ZAB power output. A quasi-solid electrolyte (QSE) based on sodium alginate (SA) is developed to address these challenges. The high concentration of KOH inhibited SA ionization which resulted in entangled SA aggregates in the QSE. The deformability and form stability of the QSE helped generate and maintain numerous air pockets at the electrolyte-cathode interface. Despite extremely low catalyst loading of 0.04 mgPt cm−2, the ZAB achieved a power density of 233 mW cm−2 at room temperature and excellent cycling stability over 480 h at −20 °C. This work provides valuable insights into designing efficient ZABs for low-temperature applications, offering a promising solution for harsh climate environments.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"67 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although hundreds of studies are devoted to understanding the mechanisms and developing high-performance vanadium-based cathodes, many puzzles and controversies still exist, especially regarding the two representative by-products, basic zinc salt (BZS) and zinc pyrovanadate (ZVO). BZS and ZVO are often observed on vanadium-based cathode and zinc anode during cycling, directly affecting battery performance. However, the two by-products’ controversial and unclassified insights and unclear mechanisms have severely limited the Zn-V batteries’ progress. Therefore, this review aims to exhaustively elucidate the “past and present” of the two by-products following a logical sequence of origin, role, inhibition strategy, and prospect.
