Abstract The efficient capture, conversion, and storage of solar energy present significant promise for advancing green utilization. However, pristine phase change materials (PCMs) are inherently inadequate optical capture absorption. To improve photothermal conversion properties, PCMs metal‐organic frameworks derived Co nanoparticle‐anchored carbonized hollow fiber advantageously integrated. robust carbon tubular structure promises thermal storage, fast phonon transfer, excellent durability structural stability after long heating‐cooling cycles. Plasmonic nanoparticles broadband‐absorbing high graphitized synergistically enhance light harvesting in composite PCMs, achieving 94.38% efficiency (100 mW cm −2 ). This integration enables the simultaneous generation electrical under randomly incident radiation. Attractively, designed photothermoelectric system steadily realizes a continuous output voltage 309.8 mV current 70.0 mA advantageous integrated design strategy provides constructive insights developing next‐generation toward systems.

Solar-driven thermo-electric generation (STEG) emerges as a promising solution to mitigate the global energy shortage. However, practical application of conventional photothermal materials equipped with STEG is limited due low solar thermal conversion efficiency. Herein, we fabricated an epoxy resin (EP) nanocomposite, EP/CCA80, excellent photo-thermal-electric properties by embedding vertically aligned aerogel consisting cellulose nanofibers (CNF) and carboxylated multi-walled carbon nanotubes (CMWCNTs) into transparent EP matrix. EP/CCA80 composites possessed broad light absorption range from 200 nm 2500 properties. Under illumination 1.0 kW m–2, achieved notable stable temperature 93.2°C efficiency up 54.35% only 0.65 wt% CMWCNTs inclusion. Additionally, coupled thermoelectric (TE) devices, composite facilitated significant difference voltage output 25.3°C 160.29 mV (1.0 m–2), respectively, which could power small fan rotate at speed 193 min–1. Such are poised offer viable solutions for enhancing accessibility in remote regions, thereby contributing reduction shortages environmental degradation.

As a renewable alternative heat source, the inherently intermittent feature of solar energy needs to be coordinated by reliable conversion and storage systems for utilizing most abundant energy. Phase change materials (PCMs) are supposed advanced mediums storing great deal generated light. However, PCMs cannot effectively absorb utilize due leakage, low photothermal efficiency, poor thermal conductivity. Herein, we developed collagen-based aerogel modified dialdehyde carboxymethyl cellulose polydopamine-modified two-dimensional transition-metal carbide/nitride (MXene@PDA) through bidirectional freeze-drying technology supporting PCMs, which exhibited anisotropy in structure properties. In particular, conductivity was 0.0871 W/(m·K) axial direction 0.0504 radial direction, demonstrating its anisotropic insulation performance. Moreover, final composite had been obtained via impregnating matrix into polyethylene glycol (PEG) hydrophobic treatment polydimethylsiloxane, outstanding solar-thermal ability, good capacity, leakage-proof property, antifouling The loading rate PEG as high 92.2%, melting enthalpy 132.6 J/g. Most importantly, water contact angle evaluated 156.8°, indicating superior This material has intensive application prospects fields collection, conversion, storage.
