A novel approach is reported to integrate CoFe‐LDH/NiAl‐LDH heterostructure through a single‐step in situ transmogrification, harnessing the benefits of LDH. The in situ Raman spectroscopy reveals that aluminum (Al) doping promotes the formation of high‐valent CoIII/IV‐O active species concentration in LDH, whereas without Al dopants, the catalyst predominantly exhibit NiII/III‐O species and underperform the catalytic activity. The projected density of states is very close to the Fermi level positions in Al‐doped samples which significantly enhance the electron transfer processes. The Mott–Schottky studies confirm that both Al40 CoFe30 and Al60 CoFe20 catalysts are p‐type semiconductors, exhibiting a distinct redox behaviors under applied bias. At positive bias, Al60 CoFe20 undergoes downward band bending (accumulation), and align the Fermi‐level near the water oxidation potential, which promotes the oxygen evolution reaction (OER). The negative bias causes upward band bending (deep depletion) in the Al40 CoFe30, and shifts the Fermi‐level near the water reduction potential, and hence facilitates hydrogen evolution reaction (HER). Overall, this study highlights the importance of manipulating Fermi‐level alignment in LDH catalysts through strategic metal doping to achieve targeted water‐splitting reactions.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"19 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142776781","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, balancing power conversion efficiency (PCE), visible light transmittance (VLT), infrared radiation rejection (IRR), and color rendering index (CRI) for window applications remains a significant challenge. In this study, ST-OPVs are developed that feature innovative near-infrared-absorbing materials. These devices are further coupled with an optical layer optimized through high-throughput optical modeling to fine-tune and enhance the different properties of the ST-OPVs. Specifically, ST-OPVs are achieved with a VLT of over 30%, a PCE of 12.5%, an IRR of over 90%, and a CRI of over 80. Furthermore, higher PCE of over 14% and IRR of over 95% can also be achieved, demonstrating the tunability of these photovoltaic properties. These figures highlight the exceptional performance of specialized ST-OPVs for window applications, demonstrating their dual function of generating electricity and energy saving. Additionally, simulations show that replacing traditional heat insulation films with the ST-OPVs can reduce annual energy demand by up to 60%, using Hong Kong as an example, underscoring their significant potential in sustainable building-integrated photovoltaic (BIPV) applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"17 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777409","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, complex processes, high costs, and insufficient yields of their preparation methods limit further application. Herein, an efficient and effective oil bath method is presented for the preparation of CaV6O16·2.7H2O (CaVO), offering promising performance as cathode material for AZMBs. With commercial crystalline V2O5, Ca(CH3COO)2, and water as raw materials, phase-pure CaVO with 42.8 g per batch and a yield of 98.8% can be obtained through the reaction at 90 °C for 6 h. It is further demonstrated that the pre-intercalated Ca2+ and H2O not only expand the interlayer spacing from 4.38 Å for V2O5 to 8.21 Å for CaVO but also stabilize the interlayer structure of vanadium oxides, promoting the reversibility of CaVO toward the de-/intercalation of Zn2+/H+. In addition, density-functional theory calculations show that the introduction of Ca2+ and H2O effectively improves the diffusion kinetics of Zn2+ in CaVO. As a result, CaVO provides high specific capacity (379 mAh g−1 at 0.05 A g−1) and promising long-term cyclability (94.4% capacity retention after 2200 cycles at 1 A g−1), demonstrating the efficient and effective synthesis of vanadium oxide-based cathode materials for high-performance AZMBs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"31 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777410","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}

In this study, manipulating the conjugation extension in poly(triaryl amine) (PTAA) derivatives by cyclic alkoxylation of side benzene groups with benzo[d][1,3]dioxole (PTAAO5) and dihydrobenzo[b][1,4]dioxine (PTAAO6) is focused on. PTAAO6 exhibits extended π-conjugation within the side groups, leading to improved energy level alignment with perovskite and enhanced charge carrier transport compared to both PTAA and PTAAO5. This strong conjugation also promotes interactions between PTAAO6 and the perovskite, resulting in larger grain sizes with reduced defects within the perovskite layer. Therefore, PSCs incorporating PTAAO6 as the HTM achieve an outstanding power conversion efficiency of 25.19%, along with excellent operational stability, retaining 90.2% of the initial PCE after 1000 h under ISOS-L-3 testing conditions. These results underscore cyclic alkoxylation as a promising approach for tailoring polymer HTMs and provide crucial insights for designing high-performance PSCs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"51 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777414","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}

Notably, Ru-Ni3Se2/FeSe2 nanosheets exhibit excellent HER (43 mV@10 mA cm−2) and OER (283 mV@100 mA cm−2) activities in alkaline solution.
