“…Specifically, over the past decade, the need for alternate daytime and night-time cooling solutions for buildings, solar cells, and electronic devices has created an increased interest in passive radiative cooling approaches (Raman et al, 2014;Sun et al, 2017;Wang et al, 2021). Designer nanophotonic systems have been employed to realize radiative cooling (Assawaworrarit, Omair and Fan, 2022;Choi et al, 2022;Fan and Li, 2022;Li et al, 2022;Didari-Bader and Menguc, 2023) through selective design approaches that involve a combination of carefully selected materials and engineered structural parameters. Metamaterials, metasurfaces, and multilayered thin-film structures (Kecebas et al, 2017;Didari and Mengüç, 2018;Bijarniya, Sarkar and Maiti, 2020;Perrakis et al, 2020;Kim et al, 2021;Yin et al, 2021;Araki and Zhang, 2022;Chamoli et al, 2022;Jin, Jeong and Yu, 2022;Lee et al, 2022;Cai et al, 2018;Gentle et al, 2018;Sun et al, 2018a;Zhao et al, 2020;Qin et al, 2022;Sun et al, 2022a;Sun et al, 2022b) have been explored for realizing temperature-adaptive devices for radiative cooling purposes.…”

In this work, we investigate a class of planar photonic structures operating as passive thermoregulators. The radiative cooling process is adjusted through the incorporation of a phase change material (Vanadium Dioxide, VO2) in conjunction with a layer of transparent conductive oxide (Aluminum-doped Zinc Oxide, AZO). VO2 is known to undergo a phase transition from the “dielectric” phase to the “plasmonic” or “metallic” phase at a critical temperature close to 68°C. In addition, AZO shows plasmonic properties at the long-wave infrared spectrum, which, combined with VO2, provides a rich platform to achieve low reflections across the atmospheric transparency window, as demanded in radiative cooling applications, while also maintaining a compact size. Using numerical analysis, we study two classes of patterned and non-patterned compact multilayer metal-dielectric-metal metasurfaces, aiming to maximize the overall absorption in the first atmospheric transparency window (8–13 µm) while maintaining a high reflection across the solar spectrum (0.3–2.5 µm). Surfaces are initially designed based on a round of coarse optimization and further improved through analyzing the impact of geometric parameters such as size and periodicity of the metasurface elements. Our findings are relevant to applications in thermal regulation systems and passive radiative cooling of high-temperature devices, such as electronic elements.
