摘要：The use of radiative cooling technology to generate electricity from vapor is a promising solution to address the energy crisis. However, existing integrated devices still suffer from poor thermal-mass kinetics and low power output. Herein, an integrated configuration was proposed to convert natural wood into a hygroscopic cooling wood hydro-aerogel (HCW) via cell wall engineering and gel co-assembly. The formation of a partially saturated interpenetrating hygroscopic network in radiative cooling wood, which regulates the water absorption-evaporation process and facilitates directional infrared radiation transfer, can effectively decouple power generation from external humidity variations during daytime. With vapor-driven hybrid passive cooling enabled by optimized thermal-mass kinetics, the HCW device unit (1 cm2) can continuously generate 0.87 V, deliver a maximum power density of 56 μW cm?2, and operate steadily outdoors for 7 days without structural shrinkage. This work paves the way for the development of advanced, sustainable, and structurally stable energy-harvesting materials. ? 2025 Elsevier Inc.
