Windows, in particular, enhance indoor brightness but also lead to increased energy loss, especially in sunny weather. Developing a product that can maintain indoor brightness while reducing energy consumption is a challenge. We developed a facile, spectrally selective transparent ultrahigh-molecular-weight polyethylene composite film to address this trade-off. It is based on a blend of antimony-doped tin oxide and then spin-coated hydrophobic fumed silica, achieving a high visible light transmittance (&gt; 70%) and high shielding rates for ultraviolet (&gt; 90%) and near-infrared (&gt; 70%). When applied to the acrylic window of containers and placed outside, this film can cause a 10 °C temperature drop compared to a pure polymer film. Moreover, in building energy simulations, the annual energy savings could be between 14.1% ~ 31.9% per year. The development of energy-efficient and eco-friendly transparent films is crucial for reducing energy consumption and promoting sustainability in the window environment. </p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":""},"PeriodicalIF":26.6,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01668-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we unprecedentedly introduced an electric ambipolar effect for synergistic manipulation on Zn<sup>2+</sup> ternary-hydrated eutectic electrolyte (ZTE) enabling high-performance Zn-Br<sub>2</sub> batteries. The electric ambipolar effect motivates strong dipole interactions among hydrated perchlorates and bipolar ligands of L-carnitine (L-CN) and sulfamide, which reorganized primary cations solvation sheath in a manner of forming Zn[(L-CN)(SA)(H<sub>2</sub>O)<sub>4</sub>]<sup>2+</sup> configuration and dynamically restricting desolvated H<sub>2</sub>O molecules, thus ensuring a broadened electrochemical window of 2.9 V coupled with high ionic conductivity. Noticeably, L-CN affords an electrostatic shielding effect and an <i>in situ</i> construction of organic–inorganic interphase, endowing oriented Zn anode plating/stripping reversibly for over 2400 h. Therefore, with the synergy of electro/nucleophilicity and exceptional compatibility, the ZTE electrolyte dynamically boosts the conversion redox of Zn-Br<sub>2</sub> batteries in terms of high specific capacity and stable cycling performance.

Herein, a series of halide ions (Cl<sup>−</sup>, Br<sup>−</sup>, I<sup>−</sup>) substituted piperazinium salts are designed and synthesized as post-treatment modifiers for perovskite surfaces. Notably, piperazinium chloride induces an asymmetric bidirectional ions distribution from the top to the bottom surface, with large piperazinium cations concentrating at the perovskite surface and small chloride anions migrating downward to accumulate at the buried interface. This results in effective dual-interface defect passivation and energy band modulation, enabling wide-bandgap (1.68 eV) perovskite solar cells to achieve a PCE of 22.3% and a record product of open-circuit voltage × fill factor (84.4% relative to the Shockley–Queisser limit). Furthermore, the device retains 91.3% of its initial efficiency after 1200 h of maximum power point tracking without encapsulation. When integrated with double-textured silicon heterojunction solar cells, a remarkable PCE of 31.5% is achieved for a 1.04 cm<sup>2</sup> monolithic perovskite/silicon tandem solar cell, exhibiting excellent long-term operational stability (<i>T</i><sub>80</sub> = 755 h) without encapsulation in ambient air.

When the molecular weight of PDVB-<i>co</i>-PACl is 5100 g mol<sup>−1</sup> and the grafting density is 0.8 wt%, the composites containing 75 wt% of AlN@PDVB-<i>co</i>-PACl exhibit the optimal comprehensive performance. The thermal conductivity (<i>λ</i>) of the composite is 1.14 W m<sup>−1</sup> K<sup>−1</sup>, which enhances by 20% and 420% compared to the <i>λ</i> of simply physically blended AlN/PMHS composite and pure PMHS, respectively. Meanwhile, AlN@PDVB-<i>co</i>-PACl/PMHS composites display remarkable hydrothermal aging resistance by retaining 99.1% of its <i>λ</i> after soaking in 90 °C deionized water for 80 h, whereas the <i>λ</i> of the blended AlN/PMHS composites decreases sharply to 93.7%.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"17 1","pages":""},"PeriodicalIF":26.6,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01669-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143184627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
