However, SnO<sub>2</sub> films from the conventional chemical bath deposition (CBD) are limited by impurities and defects that accelerate non-radiative recombination and compromise device stability. Here, we present a volatile additive engineering strategy using pyruvic acid (PA) as a dual-functional nucleation promoter and surface modulator during SnO<sub>2</sub> deposition. Owing to its volatility (sublimation at 145°C), PA can be effectively removed during annealing, resulting in cleaner SnO<sub>2</sub> surfaces with reduced residual groups.

This improvement leads to enhanced charge recombination and improved thermal stability at the buried interface. Consequently, PA-engineered PSCs achieve a power conversion efficiency of 26.17%, together with improved device stability, retaining >80% of their initial efficiency after 900 h of continuous operation, 1000 h at 65°C, and 30 days under 30% relative humidity.

These are often treated as competing frameworks for the interpretation of seemingly similar experimental observations. Here, we argue that progress in the field is limited due to an intertwining of kinetic and thermodynamic aspects of segregation and encourage the use of a generalized thermodynamic description in which different microscopic models correspond to different ways of modifying the free-energy balance under illumination. We therefore analyze the assumptions, predictions, and experimental signatures of the most widely discussed mechanisms. We further identify key limitations in current experimental approaches, mostly associated with an overreliance on photoluminescence as a characterization tool, and how variations in experimental conditions further obscure comparison across studies.

This conflict creates a “stability paradox”: the pursuit of high energy density amplifies interfacial instability, leading to inhomogeneous sodium deposition and rapid capacity decay. This review systematically analyzes AFSMB failure mechanisms under extreme conditions and demonstrates that overcoming these bottlenecks requires integrated co-design across four synergistic domains: (1) engineering electrolyte solvation structures (weakly solvating, high-concentration, and high-entropy designs) to lower the desolvation barrier and stabilize the solid–electrolyte interphase; (2) tailoring current collector interfaces with sodiophilic coatings or three-dimensional architectures to guide uniform sodium deposition; (3) incorporating rational pre-sodiation strategies to compensate irreversible sodium loss; and (4) leveraging artificial intelligence and molecular simulations for data-driven electrolyte screening. We critically assess the trade-offs of each strategy and provide a forward-looking perspective on reversible sodium compensation, multi-scale AI platforms, and full-cell integration.

By utilizing the π−π stacking between benzylideneacetone (BA) and 2‐naphthol polyoxyethylene (NPE), insoluble BA molecules form nanoaggregates with NPE and are stably dispersed within the aqueous electrolyte. At both interfaces, the BA−NPE nanoaggregates form hydrophobic interfacial layers that prevent water attack, thereby effectively suppressing side reactions.

Herein, we present experimental and theoretical studies of 28 distinct non‐fullerene acceptors (NFAs) to elucidate the relationships between molecular structure, intermolecular interaction, and morphological stability of BHJ blends, covering the well‐known indacenodithieno[3,2‐ b ]thiophene‐based (ITIC‐series) acceptors, indacenodithiophene‐based (IEICO‐series) acceptors, and state‐of‐the‐art Y‐series and dimer/trimer acceptors. We demonstrate that structural modifications of NFAs not only modulate the homo‐interaction energies between acceptor molecules but also fine‐tune their hetero‐interaction energies with donors, thereby governing the stability of BHJ nanostructures. Thermally stable BHJ blends necessitate strong homo‐interactions while minimizing hetero‐interactions to suppress NFA diffusion within the blends. The proposed intermolecular interaction effect on thermal stability is further validated by 13 literature‐reported NFA blends, demonstrating the broad applicability. These findings underscore the pivotal role of NFA structural engineering in regulating intermolecular interactions and offer valuable insights into balancing homo‐ and hetero‐interactions for the rational molecular design of thermally stable organic semiconductor blends.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"47 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172679","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}
