Passive daytime radiative cooling is of tremendous interest but would overcool during cold nights or winter days, exacerbating the heating cost, especially in high-latitude areas. Integrating the heating and cooling in one photothermal system can avoid cooling penalties and potential barriers for wide practical scenarios. Herein, we demonstrate a trilayer structure with visible and infrared spectral engineering for all-season radiative cooling and heating. The cooling mode with a solar reflectivity of 0.95 and a mid-infrared emissivity of 0.98 endows a comparable daytime subambient cooling of 9.8 °C with a theoretically net cooling power of 76.6 W/m2. Meanwhile, the heating mode with a solar absorptivity of 0.88 and a mid-infrared emissivity of 0.28 yields a daytime above-ambient heating of 16.3 °C with a theoretical net heating power of 667.8 W/m2. Promisingly, the surface binary microsphere array further enhances the mid-infrared emissivity, superhydrophobicity, and environmental durability, making the trilayer structure a viable pathway for thermal management with great potential in electricity savings and CO2 emission reduction. This work offers new possibilities for designing next-generation radiative cooling materials, greatly widening the scope of use.
