Metal halide perovskite photovoltaics have achieved power conversion efficiencies rivaling crystalline silicon, yet their transition from laboratory-scale devices to commercial deployment requires a paradigm shift toward application-specific engineering and macroscopic system integration. This review systematically evaluates the customized deployment of perovskite solar cells (PSCs) across diverse operational theaters, including building-integrated photovoltaics (BIPV), portable Internet of Things (IoT) systems, agricultural photovoltaics (Agri-PV), vehicle-integrated photovoltaics (VIPV), utility-scale tandems, and extreme space environments. Despite these opportunities, critical challenges persist in translating laboratory achievements into industrial-scale production. We critically evaluate primary bottlenecks hindering gigawatt-scale commercialization, focusing on the performance gap inherent in large-area manufacturing. Additionally, we analyze intrinsic material instabilities driven by dynamic ion migration and multi-scale lattice strain under realistic outdoor conditions. To conclude, we outline a strategic roadmap for overcoming these barriers, emphasizing lattice strain regulation, rigorous dynamic environmental testing protocols, and comprehensive sustainable lifecycle management. By synergizing mechanistic insights with scalable manufacturing and ecological assessments, this review provides a holistic framework to accelerate the ubiquitous commercialization of customizable, stable, and high-efficiency perovskite energy systems.

Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial lung disease with high mortality and limited therapeutic options. Dysregulated macrophage polarization drives fibroblast activation and epithelial-mesenchymal transition (EMT), yet no effective management exists. Here, we develop an inhalable methane nanocapsule (MNC) that spatiotemporally controls methane release in the lung to remodel the fibrogenic microenvironment. MNC is formulated via self-assembly of biodegradable poly(lactic-co-glycolic acid)-polyethylene glycol (PLGA-PEG) and a novel acid-responsive methane prodrug Fe(BPY)2(CH3)2, enhancing mucosal penetration and sustained methane release in acidic inflammatory niches. In a bleomycin (BLM)-induced pulmonary fibrosis model, MNC inhalation achieves efficient lung deposition and sustained methane release, significantly reducing inflammation, ameliorating fibrosis, and improving lung function without systemic side effects. Mechanistically, MNC rebalances macrophage polarization by inhibiting M2 phenotype overexpression and downregulates the MMP9/TIMP-1 ratio to suppress myofibroblast proliferation and EMT, synergistically halting fibrotic progression. This inhalable methane nanocapsule offers a promising strategy for safe and effective IPF treatment.

This study reports the synthesis of a novel Z-scheme heterojunction composite film comprising Ag/Bi2MoO6/BiOBr via electrochemical processes, ion-exchange techniques, and subsequent photodeposition of silver nanoparticles. The incorporation of Ag nanoparticles exploits localized surface plasmon resonance (LSPR) effects and serves as an electron mediator, establishing a Schottky barrier that suppresses charge recombination. The optimized 1.5% Ag/Bi2MoO6/BiOBr film achieves a CO production rate of 13.65 μmol/(g·h) from photocatalytic CO2 reduction, significantly outperforming the unmodified Bi2MoO6/BiOBr film. Photocurrent and impedance analyses confirm enhanced charge separation in the Ag-modified composite. A non-linear relationship between Ag loading and photocatalytic efficiency was observed, with optimal performance at 1.5% Ag. The proposed Z-scheme mechanism elucidates the synergistic interactions among components, providing a scientific basis for rational design of advanced photocatalysts and immobilized systems for CO2 reduction. This work offers insights into the development of efficient, sustainable photocatalytic technologies for carbon capture and utilization.

Leuco dye-based thermochromic fibers suffer from poor light fastness, limiting their cyclability. Here, a hydrogen bond dissociation/structural isomerization-based dual ultraviolet (UV)-shielding strategy is proposed to develop enhanced light-resistant thermochromic elastomer fibers (Azo/TCM@Abs/TPU) employing UV absorbers and 4-dodecyloxyazobenzene (C12-Azo) through a coaxial wet-spinning process. The integration of UV absorbers and C12-Azo enhances UV protection, effectively blocking nearly the entire UV spectrum. The light fastness of Azo/TCM@Abs/TPU has been improved to Grades 3–4, enabling a stable thermochromic function to withstand several months of sunlight exposure. Additionally, the absorbed UV light is stored as chemical energy within C12-Azo via trans-to-cis photoisomerization. This stored energy can be released as heat on demand. The coaxial dual-protection concept using photoisomerization offers an efficient method to enhance light resistance in thermochromic fibers.

The escalating global generation of waste plastics necessitates robust recycling strategies to mitigate environmental impact and advance low-carbon development. This study employs life cycle assessment (LCA) and emission factor methodologies to quantify the carbon footprints of six distinct waste plastic valorization pathways: mechanical recycling, pyrolysis, alcoholysis, co-coking, solid fuel production, and direct incineration. The functional unit is one tonne of waste plastic, with system boundaries encompassing transportation, pretreatment, and resource utilization. The model accounts for indirect emissions from energy consumption, direct emissions from plastic decomposition, and carbon offsets from material or energy recovery. Results indicate that pyrolysis yields the highest carbon offset of approximately -3,024 kgCO2e per tonne, while mechanical recycling achieves an 88% material recovery rate and a net carbon offset of -991.4 kgCO2e. Net carbon emissions per tonne of waste plastic rank as follows: direct incineration (1,104 kgCO2e) > co-coking (185.8 kgCO2e) > solid fuel (115.4 kgCO2e) > alcoholysis (-259.5 kgCO2e) > mechanical recycling (-991.4 kgCO2e) > pyrolysis (-2,592 kgCO2e). These findings demonstrate that pyrolysis offers superior carbon reduction benefits compared to incineration, exhibiting a net-negative carbon footprint across its life cycle. The study provides a scientific basis for selecting low-carbon waste plastic valorization routes and informs carbon trading and emission reduction strategies in the solid waste sector.

Lung cancer, particularly non-small cell lung cancer (NSCLC), remains a leading cause of cancer-related mortality, with conventional therapies hampered by poor tumor specificity, low drug accumulation, and suboptimal efficacy. To address these challenges, we rationally designed a tumor-targeted, ferrocene-bearing, covalently immobilizable theranostic probe, dIR-CDF, for near-infrared (NIR) imaging-guided photodynamic-ferroptosis synergistic therapy. The probe exploits the overexpression of sulfenated proteins in the tumor microenvironment to specifically target integrin αvβ3-positive NSCLC cells and undergo covalent anchoring via the reaction between 1,3-cyclohexanedione and sulfenic acid, thereby enhancing tumor accumulation and retention. Under 808 nm irradiation, dIR-CDF generates singlet oxygen (1O2) for photodynamic therapy (PDT), while the sustained release of ferrocene catalyzes Fenton reactions to produce hydroxyl radicals (·OH), inducing ferroptosis. The synergistic action of PDT and ferroptosis amplifies lipid peroxidation and disrupts antioxidant defenses, leading to efficient suppression of NSCLC tumors in living mice. This work presents a universal and powerful theranostic platform for precise cancer diagnosis and treatment, with the covalent targeting strategy offering enhanced specificity and retention.
