Photon-Enhanced Thermionic Emission (PETE) has emerged as a hybrid conversion concept that synergistically combines photonic and thermal excitation of charge carriers in semiconductors to emit electrons across a vacuum gap, thereby generating electrical power. This review offers a detailed report of PETE device architectures, with a particular focus on recent advancements in cathode and anode materials, heterostructure engineering, and design innovations focusing at enhancing device performance. Critical operational parameters are investigated for their impact on power conversion efficiency, including temperature control, space-charge effects, vacuum-gap, intrinsic material properties, and optical characteristics. This review also highlights current research challenges to be addressed to advance PETE technology to practical implementation. These comprises of development of thermally stable cathode materials with lower electron affinity, anodes with low work functions, and robust thermal management strategies to maintain optimal operating conditions. Furthermore, the optimization of optical designs to maximize photon absorption and the capability to operate efficiently under high photon flux conditions are identified as key areas of research for future investigation. By identifying key material bottlenecks, device constraints, and realistic performance limits, this Review establishes material selection and device design guidelines for future research on scalable high-temperature solar energy technologies compatible with emerging net-zero energy pathways.</div></div>","PeriodicalId":295,"journal":{"name":"Current Opinion in Solid State & Materials Science","volume":"44 ","pages":"Article 101293"},"PeriodicalIF":14.1,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148854013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines WAAM lattice structures across slicing and toolpath planning, fabrication strategy, lattice design, fabrication quality analysis, mechanical performance, finite element modelling, applications, and standardisation. Existing studies have demonstrated mainly strut-based lattices in steels, aluminium alloys, titanium alloys, and copper-based alloys, with mechanical performance evaluated through tensile, compression, bending, and hardness testing at both strut and lattice scales. Finite element models can capture case-specific stress and thermal trends, but their predictive accuracy remains limited by nominal digitally-designedgeometry, simplified constitutive behaviour, insufficient node morphology, and weak thermal-history coupling. Demonstrated and prospective applications include civil construction, aerospace, marine engineering, and energy absorption. However, broader implementation is still constrained by immature lattice-aware slicing, gravity-induced strut instability, node control, restricted topology diversity, and inconsistent terminology. Mechanical testing should draw on existing additive manufacturing, cellular-metal, tensile and bending standards, but these frameworks must be adapted before they can serve as qualification protocols for WAAM lattices.</div></div>","PeriodicalId":295,"journal":{"name":"Current Opinion in Solid State & Materials Science","volume":"43 ","pages":"Article 101284"},"PeriodicalIF":14.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148656674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
