This review provides a comprehensive overview of recent advances in green and renewable processing strategies for metal halide perovskites, with a particular focus on environmentally benign material design and device fabrication. We first discuss the development of non-toxic, lead-free perovskite materials, highlighting the most promising candidates based on performance, stability, and elemental abundance. Subsequently, progress in green solvent engineering, including bio-derived and low-toxicity solvent systems, is summarized with an emphasis on solvent–perovskite interactions and process compatibility. We then examine green and low-energy fabrication processes, such as low-temperature, vacuum-free, and scalable coating techniques, which significantly reduce energy consumption and carbon footprint. The importance of intrinsic material stability is further discussed as a key criterion for sustainable perovskite technologies, as prolonged operational lifetimes directly translate into reduced environmental impact. Finally, emerging recycling and circular-economy strategies for perovskite devices are reviewed, addressing material recovery, substrate reuse, and end-of-life considerations. By integrating material, process, stability, and recycling perspectives, this review outlines a holistic framework toward truly sustainable metal halide perovskite technologies.</p>\u0000 </div>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 38","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149206178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complementary FTIR and XPS analyses reveal carbazole-derived vibrational features and additive-dependent perturbations of the nitrogen and lead electronic environments, establishing a comparative sequence of molecular association with the PQD surface.

This pronounced interfacial interaction is accompanied by the most substantial improvements in the photophysical characteristics of the PQDs and the electroluminescent performance of the resulting PeLEDs. The extended π-conjugated framework further facilitates interfacial charge transport and radiative recombination in green-emissive PeLEDs. As a result, MCP-based PeLEDs exhibit an enhanced peak external quantum efficiency from 11.77% to 19.43%, together with a maximum luminance of 46434 cd/m<sup>2</sup>.

In parallel, 2PACz-mediated energy-level modulation facilitates hole injection and suppresses excessive electron injection, improving carrier balance in inverted red InP-based QLEDs. The resulting devices achieved a peak external quantum efficiency of 23.7% and an extrapolated half-lifetime of 217.8 h at an initial luminance of 1000 cd m<sup>−2</sup>.

Rather than starting from a predefined photonic lattice and adapting optical pathways to its geometric constraints, the proposed approach inverts this logic by prescribing the desired optical path first and then constructing the surrounding dielectric environment locally to support guided transport. This pathway-first strategy enables arbitrarily shaped guiding channels protected by a photonic bandgap, maintaining high transmission through bends and complex geometries without reliance on lattice symmetry directions. Within this unified framework, conventional photonic crystal waveguides emerge naturally as special cases, while genuinely freeform interconnects that are inaccessible within periodic architectures become systematically realizable. Finite-difference time-domain simulations demonstrate robust guidance and high transmission within a well-defined low-loss spectral window for realistic material platforms. These predictions are validated experimentally through near-infrared measurements on silicon membrane devices and mm-scale experiments on 3D-printed ceramic slabs, which directly confirm low-loss transmission and field confinement along freeform pathways. Together, these results establish an experimentally grounded design paradigm for disorder-engineered photonic interconnects, identifying HUD-based freeform architectures as a flexible and scalable foundation for compact, high-density integrated photonic circuits beyond the constraints of periodic design.</p>","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"14 37","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.71768","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149125887","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}
