This study demonstrates unique advantages of fluoroalkyl hybrid glycol ether side chains of naphthalene diimide (NDI)-based electron transport layers (ETLs) compared to their counterpart (P3O) without fluoroalkyl terminals. First, the fluoroalkyl hybrid glycol ether side chains shift the polymer chain orientation from edge-on in P3O to face-on in P3F, P5F, and P7F, thereby accelerating charge transport. Second, they introduce interfacial dipoles that passivate defects at the perovskite surface, generating an additional electric field that improves electron transfer efficiency. Third, they remarkably enhance the moisture resistance of ETLs and the ambient stability of Dion-Jacobson hybrid perovskite solar cells (DJHPSCs). Consequently, NDI-polymers with fluoroalkyl hybrid glycol ether side chains remarkably improved the power conversion efficiency (PCE) and lifetime of the DJHPSCs compared to the counterpart using P3O. For instance, P3F as ETL yields a power conversion efficiency (PCE) of 14.21 % and allows the device to retain 80.2 % of its initial PCE after 2077 h of air exposure. This represents a remarkable improvement in both PCE and lifetime compared to the device using P3O as ETL, which delivers a low PCE of 11.14 %, and retains 48 % of its initial value after 1740 h of air exposure.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"150 ","pages":"Article 111753"},"PeriodicalIF":17.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146047820","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}

Although surface engineering is a critical determinant of TENG output performance, predominant strategies are largely confined to static structural designs. Consequently, effective approaches for the dynamic tuning of the contact interface remain limited. Inspired by the natural venation topology of leaves, this work fabricates a rhombic-patterned array on the surface of triboelectric layers via one-step template-assisted electrospinning, facilitating the formation of moiré fringes through interlayer rotation. Rotating the two triboelectric layers to predetermined angles (0°, 45°, and 90°) modulates the period and distribution of the moiré fringes, leading to distinct geometric configurations at the contact interface. This angle-dependent variation of the moiré geometry enables controllable regulation of the effective interfacial contact area, thereby yielding a tunable electrical output. This direct correlation further validates the device's capability for angle sensing. Compared with the TENG based on flat nanofiber membranes, the patterned TENG exhibited a significant short-circuit current enhancement of approximately 306 %, attributed to the synergistic effect of the bio-inspired microstructure and this tunable moiré modulation.

To address this issue, liquid or solid additives are commonly introduced during film fabrication; however, the mechanisms by which different additives regulate NFA aggregation remain elusive. Herein, the relationship between photovoltaic performance and NFA aggregation in the state-of-the-art PM6/L8-BO blend systems is investigated using 1,8-diiodooctane (DIO, liquid additive) and 1,4-diiodobenzene (DIB, solid additive) as representative additives. As a result, DIO is found to promote excessive L8-BO aggregation, leading to reduced photoluminescence quenching efficiency and charge mobility, which deteriorates photovoltaic performance. In contrast, DIB does not directly promote aggregation but acts as a plasticizer for PM6, lowering its glass transition temperature, and thereby enabling controlled L8-BO aggregation during thermal annealing. In-situ absorption spectroscopy during spin coating suggests that DIO facilitates liquid–liquid phase separation, whereas DIB regulates aggregation indirectly through polymer softening. These findings clarify the distinct roles of liquid and solid additives in morphology regulation, providing new insights for designing highly efficient OPVs via precise control of active layer aggregation.</div></div>","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"150 ","pages":"Article 111775"},"PeriodicalIF":17.1,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146122285","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}
