Herein, we report a synergistic strategy that integrates nanoimprinted p-type two-dimensional (2D) metal halide perovskite scaffolds with ternary-blended n-type organic layers to construct ordered embedded heterojunction photovoltaic devices. Optimized nanoimprinting converts the planar p-type crystalline layer into highly ordered nanohole arrays while preserving crystalline continuity, improving film morphology, and suppressing defect states. The resulting nanohole architecture enhances broadband absorption over 400–900 nm through optical-field localization and multiple scattering. Meanwhile, the enlarged p/n interfacial contact and ordered charge-transport pathways promote carrier extraction, increase the built-in potential, reduce energetic disorder, and suppress interfacial recombination. As a result, the nanoimprinted binary device achieves a power conversion efficiency of 21.91%, exceeding that of the planar control device with 19.70%. Further incorporation of PC₇₁BM into the D18-Cl:PY-IT host blend increases the efficiency to 23.37%. Notably, the unencapsulated ternary device retains 90% of its initial efficiency after 2000 h in N₂ and over 92% after 1200 h of maximum power point tracking.

Here, a GuaSCN-assisted vacuum crystallization strategy is developed to realize efficient HTL-free and antisolvent-free Sn-Pb perovskite solar cells. The in-situ photoluminescence evolution is consistent with a cooperative crystallization process, where SCN^- regulates early-stage growth while Gua⁺ facilitates later-stage structural relaxation, enabling sustained optoelectronic improvement during film formation. This synergistic regulation yields compact Sn-Pb perovskite films with a uniform buried interface, reduced structural and compositional heterogeneity, and a surface-associated residual region that may contribute to interfacial passivation. Cross-sectional chemical mapping further shows reduced local compositional fluctuations and interfacial irregularity within the analysed regions. These structural characteristics are accompanied by increased quasi-Fermi level splitting, reduced energetic disorder, and a higher attainable photovoltage of the neat perovskite film. Consequently, HTL-free devices deliver a champion efficiency of 21.4% with a fill factor exceeding 80%, among the highest values reported for HTL-free, antisolvent-free Sn-Pb perovskite solar cells.

Nevertheless, the practical deployment of ASSFIBs is hindered by the lack of high-performance fluoride-ion solid-state electrolytes (FISSEs). Recently, rare earth (RE) elements have attracted considerable interest for advancing high-performance FISSEs by leveraging their unique physicochemical properties. To provide a timely overview of progress in this rapidly evolving field, this review examines the critical functions of RE elements in state-of-the-art FISSEs, covering both typical Tysonite-type FISSEs (e.g., LaF₃, CeF₃) and RE-doped systems (e.g., Ba₁_–_<em>x</em>Eu_<em>x</em>SnF_4+<em>x</em> and Ce₁_–_<em>y</em>Th_<em>y</em>F_3+<em>y</em>). We begin by outlining the operational mechanism of ASSFIBs, categorizing the main types of FISSEs, and evaluating their respective advantages and limitations. We then highlight recent advances in performance optimization and battery applications of RE-enhanced FISSEs. Finally, we proposed the potential future research directions for RE-containing FISSEs. Through the precision design of RE-based FISSEs and their rational pairing with electrode materials, high Coulombic efficiency and environmental friendliness can be achieved. Consequently, ASSFIBs are expected to become the next-generation energy storage technology for widespread use in electric transportation and grid-scale renewable energy storage.</div></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"169 ","pages":"Article 101189"},"PeriodicalIF":31.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146023760","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}

The existing gold standard treatment method for hydrocephalus includes surgical cerebrospinal fluid shunting with the help of “one-size-fits-all” catheters. Although this method is very efficient, following their insertion, catheters are subjected to various complications, including flow resistance, blockage, mechanical malfunctions, and being subjected to host-immune response as well as microbial infection. To overcome these complications, we proposed implementing three-dimensional (3D) printing technology to develop the next generation of catheters with improved functionality and liquid flowability. Our suggested technology is based on imaging data on the final destination site (via computed tomography scan or magnetic resonance imaging) in such a way that it fits the needs of the body in a personalized manner. Herein we report for the first time, digital light processing (DLP) 3D printing of helical-shaped, flexible catheters using commercially available KeySplint soft resin. These catheters offer fully customizable features such as diameter, the number and placement of drainage holes tailored to individual patient needs. <em>In vitro</em> stability study of the 3D printed KeySplint samples suggested that the 3D printed catheters may remain structurally stable under physiological conditions for atleast 3240 hrs (135 days). Moreover, to further enhance catheter’s functionality, a pH-responsive smart surface chemistry was introduced on the catheter surface using two strategies (via plasma coating and by simply mixing with 3D printing resin) that can respond dynamically to tackle two critical challenges related to catheters: blockage of the catheters by undesired proteins, choroid plexus, blood clots and infection/biofilm prevention via chemical intramolecular rearrangement in the functional moieties of the coating. Both CB-OH coated and 5 % CB-OH mixed 3D printed catheters significantly inhibited bacterial biofilm formation at 24, 48, and 72 hrs compared to pristine catheters. On top of that, the CB-OH coated 3D printed helical catheters showed a 37-folds reduction in particles deposition per unit volume relative to conventional 3D printed linear catheters.

However, in the preparation using halogen-free solvent, the acceptor layer struggles to fully penetrate the donor layer, leading to a reduction in donor-acceptor contact area and restricting exciton dissociation. Here, aqueous organic nanoparticles (NPs) comprising blended donor-acceptor materials are incorporated at the donor/acceptor interface in sequentially deposited green solvent-processed LBL devices. These NPs provide abundant exciton dissociation sites while their spherical morphology maximizes interfacial contact with the overlying acceptor layer. These structural features synergistically increase donor/acceptor interface, effectively mitigating the interlayer penetration deficiency in green solvent-processed LBL devices, thereby significantly enhancing exciton dissociation efficiency. Further morphological characterization confirmed that the NPs interlayer induces an improved vertical phase distribution in the photoactive layer, facilitating effective charge transport and collection. Consequently, a halogen-free LBL device constructed with the PM6/NPs/BTP-eC9 system achieved a notable power conversion efficiency (PCE) of 17.94 %. Extending this approach to the D18-Cl/L8-BO system achieved a PCE of 20.61 %, among the highest PCEs reported in halogen-free OSCs.
