Yet, their reaction to moisture remains uncertain, necessitating further exploration. While prolonged exposure to moisture can lead to degradation, it can also passivate traps at an optimal moisture level. Here, we use scanning probe microscopy to perform nanoscale moisture-dependent photovoltaic characterizations of open and compressed grain boundary (GB) structures of wide bandgap (FAPbI<sub>3</sub>)<sub>0.3</sub>(FAPbBr<sub>3</sub>)<sub>0.7</sub> perovskites. The investigation reveals a decrease in the potential barrier at compact GBs with increasing moisture levels, contrasting with the behavior observed in open GBs. Moreover, the photocurrent distribution over both samples proportionally increases when relative humidity (RH) is raised from 10% to 60%. Notably, following a 24-h exposure at RH 60%, the compact-GB sample demonstrates: i) a reduction in the density of charged trap states at GBs, ii) higher photocurrent, accompanied by a noticeable decrease in current hysteresis compared to the open GB sample, and iii) further enhancement in device efficiency and crystallinity compared to devices with open GBs. These findings suggest that optimizing humidity conditions in engineering the GB chemistry can enhance the optoelectrical properties of GBs, ultimately leading to improved device performance.</p>","PeriodicalId":11554,"journal":{"name":"Energy & Environmental Materials","volume":"9 1","pages":""},"PeriodicalIF":14.1,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eem2.12869","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145719670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed all-optically controlled synapses exhibit excellent information perception, low-level noise reduction, and high-level cognition functions for bioinformation recognition under complex light conditions.

Traditional approaches, such as alloy-based current collectors or fluorinated interfaces, often suffer from irreversible volume expansion or corrosive fabrication processes. This study introduces a solvent co-intercalation-mediated in situ sodiophilic interface engineering strategy to overcome these limitations. A graphitized carbon-modified aluminum current collector dynamically regulates interfacial evolution through solvated sodium-ion co-intercalation during initial cycling, prompting the formation of a C-NaF interface with ultralow Na<sup>+</sup> adsorption energy. This sodiophilic interface not only facilitates uniform sodium nucleation by providing abundant sodium-philic sites but also encourages the preferential decomposition of anions in the electrolyte, leading to the creation of a robust and NaF-rich solid electrolyte interphase. Consequently, the asymmetric half-cell delivers an ultralow nucleation overpotential (9.7 mV at 0.5 mA cm<sup>−2</sup>) and maintains an average coulombic efficiency of 99.8% over 400 cycles at 1 mA cm<sup>−2</sup>. When combined with a Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>2</sub>O<sub>2</sub>F (NVPOF) cathode, the full cell achieves an energy density of 363 Wh kg<sup>−1</sup> with 80% capacity retention after 250 cycles at 0.5 C.
