Donors with low synthetic complexity are desirable to lower costs. However, inverted devices are rarely used in low-complexity systems. To investigate the reasons, the low-complexity PTQ10:BTP-eC9 binary system is benchmarked against the high-complexity PM6:BTP-eC9 system. In PTQ10:BTP-eC9, where the efficiency of inverted devices lags the conventional structure significantly, distinct wetting layers are observed in conventional and inverted device structures. Conversely, the vertical distribution of PM6:BTP-eC9 remains unaffected by changes in interlayer materials. The surface is always enriched in BTP-eC9, but less for PM6. Importantly, the addition of PC71 BM reduces the nonuniform vertical composition gradients. As the PC71 BM concentration increases, the efficiency of the inverted PTQ10 devices approach that of the conventional devices and PTQ10:BTP-eC9:PC71 BM (1:1.2:0.4) exhibits negligible efficiency differences between inverted (14.01%) and conventional (14.49%) architectures. The concentration-gradients aredriven by the interfacial energy between the active layer and interlayer materials and the casting kinetics in the case of the surface. Understanding the thermodynamic and kinetic aspects provides valuable insights for optimizing the performance of inverted organic solar cells, bringing them closer to practical applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"16 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911658","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 reversibility of Zn metal anodes is limited by severe side reactions and dendritic growth, caused by interfacial concentration gradients. To address this, a Zn2+-rich zinc phytate (ZP) chelate layer is introduced as artificial solid electrolyte interphase (SEI) that eliminates these concentration gradients through ions compensation. Theoretical calculations and experimental results demonstrate that the ZP layer, rich in Zn2⁺ ions and exhibiting strong chelating ability to capture more Zn2+, enables rapid and dynamic ion replenishment at the interface, significantly improving Zn2⁺ transport kinetics and ensuring a uniform Zn2⁺ flux. Moreover, the strong chelation of PO₄ groups restricts the 2D diffusion of Zn2⁺ ions, promoting the uniform Zn deposition. Additionally, the ZP layer repels anions and restricts water molecules migration at the Zn anode surface, fundamentally suppressing side reactions. As a result, the modified Zn anode exhibits stable Zn plating/stripping for ≈2400 h at 1 mA cm−2 and 1 mAh cm−2, with an average Coulombic efficiency of 99.8%. Furthermore, the assembled ZP@Zn//VO2 cell displays 87.5% capacity retention after 6000 cycles at the current density of 5 A g−1.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"20 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917615","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 practical applications, most conductive ceramics are polycrystalline, and their overall conductivity (σtotal) is influenced by both bulk and grain boundary resistances (Rbulk and Rgb, respectively). While Rbulk is mainly of academic interest, Rgb often determines the quality of a conductive ceramic component. Currently, studies discussing the influence of specific methods on grain boundary resistances are typically related to individual ceramics. In this study, it is discovered that the addition of 0.5–3 mol% nominal LaNbO4 significantly reduces the Rgb of several well-known conductive ceramics, such as rhombohedral NaSICON-type Na+-ion-conducting Na3.4Zr2Si2.4P0.6O12 and Li+-ion conducting Li1.5Al0.5Ti1.5P3O12, Li+-ion-conducting tetragonal perovskite Li0.34La0.56TiO3, oxygen-ion-conducting cubic fluorite 8 mol% Y2O3 stabilized ZrO2, and electron-conducting perovskite SrTiO3 (sintered in a reducing atmosphere). In particular, for NZSP and LATP, the enhanced σtotal reaches 9.3 × 10−3 S cm−1 and 2.1 × 10−3 S cm−1 at 25 °C, surpassing previously published results. Detailed investigations reveal that the microstructure of the grain boundaries in all the ceramics undergoes significant improvements. The findings elevate the importance of research on grain boundaries, inspiring the development of conductive ceramics with higher σtotal for superior applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"68 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911745","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}

Here an autonomous framework driven by a machine learning (ML)-guided automated platform is introduced to optimize the fabrication conditions of additive- and passivation-free perovskite solar cells (PSCs) under ambient conditions. By effectively exploring a 6D parameter space, this method identifies five parameter sets achieving efficiencies above 23%, with a peak efficiency of 23.7% with limited experimental budgets. Feature importance analysis indicates that the rotation speeds during the first and second steps of perovskite processing are the most influential factors affecting device performance, thereby meriting prioritization in the optimization efforts. These results demonstrate the exceptional capability of the autonomous framework in addressing complex process parameter optimization challenges and its potential to advance perovskite photovoltaic technology. Beyond PSCs, this work provides a reliable and comprehensive strategy for optimizing solution-processed semiconductors and highlights the broader applications of autonomous methodologies in materials science.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"26 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911747","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}

Therefore, the development of vanadium-based cathode materials with stable crystal structures and fast Zn2+ storage remains challenging. Herein, Na2CaV4O12 (NCVO) nanowires are reported as a promising cathode of excellent electrochemical performance in AZIBs, simultaneously rendering high specific capacity (443.2 mAh g−1 at 0.1 A g−1) and high average voltage plateau (0.91 V) with impressive energy density (403.3 Wh kg−1) and power density (1533 W kg−1). As NCVO features a unique open crystal structure with alternately arranged inactive layers ([NaO6] and [CaO8] polyhedra) and active layers ([VO4] tetrahedra), the expansion of the [VO4] tetrahedra during Zn2+ insertion is well balanced by the contraction of the inactive layer, thus enabling remarkable long-term cycling stability (91.9% and 80% capacity retention after 5000 and 10 000 cycles at 10 A g−1, respectively). With the electrochromic property of the NCVO cathode, the AZIB can further be used for adaptive camouflage under a range of scenarios, shedding light on the future development of high-performance cathodes for AZIBs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"13 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917618","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 inferior performance for n-type Bi2(Te, Se)3 largely restricts the practical applications. In this study, additional Ag atoms are introduced utilizing lattice plainification strategy to enhance electrical performance. Observations indicate that Ag atoms situate in the van der Waals layers, acting as n-type dopants to increase carrier concentration, bonding with adjacent Te as intercalating atoms to form electron transport channels, while also suppressing the formation of Te vacancies to boost carrier mobility, substantially favoring carrier transport. Consequently, Bi2Te2.79Se0.21I0.004+0.3%Ag achieves an excellent room-temperature ZT of ≈1.1, while Bi2Te2.79Se0.21I0.004 + 0.4%Ag demonstrates a higher average ZT of ≈1.1 at 300–523 K. Furthermore, a full-scale thermoelectric cooler using optimized Bi2Te2.79Se0.21I0.004+0.3%Ag combined with commercial p-type Bi0.5Sb1.5Te3 has achieved a maximum cooling temperature difference (ΔTmax) of ≈68.3 K at 300 K and a larger ΔTmax of ≈84.8 K at 343 K. Additionally, the Bi2Te2.79Se0.21I0.004 + 0.4%Ag/Bi0.5Sb1.5Te3-based power generator realizes a conversion efficiency of ≈6.0% under a ΔT of ≈240 K.

This review systematically focuses on the reconstruction of cathode-electrolyte interphase maintaining the interfacial stability via various strategies at high voltage range. The state-of-the-art characterization techniques and modeling approaches associated with cathode-electrolyte interphase are also discussed. From the perspective of electrolyte design, the interphase reconstruction strategies focus on solvent molecule manipulation, solute ion manipulation, and the regulation of solvation-ion interaction.

These local structures can be likewise beneficial or detrimental to the performance, by either increasing the catalytically active area or by limiting the supply of reactants.
