In this study, a multifunctional strategy for stabilizing perovskite precursor solutions is developed, utilizing the non-steroidal anti-inflammatory drug potassium diclofenac (PD) to achieve high efficiency and exceptional thermal stability in PSCs. PD can simultaneously passivate cationic and anionic defects, delay the crystallization time between FAI and PbI₂, reduce the crystallization rate, produce larger grains and fewer grain boundaries, thereby enhancing the crystallization ability and thermal stability of perovskite. Additionally, PD can optimize the energy level alignment of devices and suppress non-radiative recombination in the devices. The resulting inverted PSCs achieve an outstanding power conversion efficiency (PCE) of 26.14 % and maintain 95 % of their initial efficiency after 2000 h under high-temperature conditions at 85 °C, demonstrating excellent thermal stability. To our knowledge, this achievement represents one of the best thermal stabilities among PSCs evaluated under the ISOS-D-2 protocol to date. Furthermore, by employing the PD modification strategy, a champion PCE of up to 25.20 % is successfully achieved in n-i-p PSCs, fully demonstrating the broad applicability of this approach. The utilization of multifunctional non-steroidal anti-inflammatory drug molecules paves a new way for developing high-performance and thermally stable PSCs.</div></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"169 ","pages":"Article 101193"},"PeriodicalIF":31.6,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146170024","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}

Consequently, additive manufacturing (AM) methods are attracting a lot of attention, taking advantage of their ability to fabricate geometrically complex Ti₂AlNb structural parts. This work comprehensively reviews recent progress in the AM of Ti₂AlNb alloys, focusing primarily on powder methods, i.e. electron beam melting (EBM), laser powder bed fusion (LPBF), and laser directed energy deposition (LDED). The relationship between AM process parameters, ensuing microstructures, and the resulting mechanical properties is systematically examined. The microstructural characteristics exhibit significant process dependency: the higher preheating temperatures and slower cooling conditions in EBM promoting O phase precipitation; whereas the rapid solidification characteristic of LPBF results in B2 phase-dominated metastable microstructures; while the layer-by-layer variation in thermal cycles experienced during LDED leads to substantially higher macro-scale microstructural heterogeneity. By examining how energy density, scanning strategy, and post-processing treatment influence phase transformation, grain morphology, and defect formation, we propose strategies to address challenges hindering broader application of AM Ti₂AlNb alloys.

However, despite the standout advantage, the commercialization of LRLO cathodes has been hindered by several intrinsic challenges, including structural evolution, significant voltage decay, capacity loss during cycling, and poor rate capability. Extensive investigations have shown that these performance issues primarily stem from the complex interfacial chemistry and structural instability of LRLO cathodes at high charge voltages (&gt; 4.6 V vs. Li/Li⁺). The review provides a systematic analysis of the structural characteristics and intrinsic advantage of LRLO cathodes, along with the mechanisms underlying the structural degradation, capacity and voltage decay, and electrolyte decomposition. The performance degradation is mainly attributed to the release of reactive oxygen species (ROSs) from LRLO cathodes, which triggers electrolyte decomposition, HF generation, and the formation of a thick cathode/electrolyte interface (CEI), leading to severe capacity fading, voltage decay, and poor rate performance. Consequently, the paper summarizes the designed and optimized electrolyte strategies in order to overcome these challenges and enhance the performance of LRLO cathodes.

Two-dimensional (2D) halide perovskites have shown promise in addressing this issue due to their enhanced moisture resistance and structural tunability. Most existing works emphasize phase types or device-level performance, but lack a molecular-level classification that links the structure of organic spacer cations to crystallization behavior, interfacial interactions, and device functionality. In this review, we construct a comprehensive, molecular-level framework for the rational design of 2D/3D hybrid perovskite systems. We systematically classify over hundred organic spacer cations across three structural dimensions—spatial geometry (e.g., linear vs. cyclic), functional group chemistry (e.g., hydroxyl, carboxyl, alkynyl), and heteroatom composition (e.g., O, N, S substitutions)—to elucidate how each structural motif governs crystallization behavior, phase formation, defect passivation, and charge transport. This structure-function map is then contextualized within four widely used heterostructure construction methods: bulk incorporation, buried interface modification, surface treatment, and vapor-phase deposition. Each strategy is evaluated in terms of its impact on film morphology, phase alignment, interfacial energetics, and scalability. This review also highlights emerging molecular designs, such as nitrogen-containing spacers lacking classical ammonium groups, which offer new opportunities for inducing layered structures and tuning optoelectronic properties. Finally, we outline future directions involving AI-guided molecular screening, entropy-driven cation engineering, and scalable deposition techniques, aiming to bridge molecular design with practical manufacturing.
