Abstract
Recently, radiative cooling has been actively studied, as objects can be cooled without using additional energy. Here, we demonstrate a new class of radiative cooler, this is silica photonic crystals, which are used for the structural colorization. The intrinsic phonon vibration of silica leads to the absorption of mid-infrared (mid-IR) waves, which in turn cool the objective in a radiative way. At daytime, these assembled photonic crystals effectively reduce the temperature of the crystalline-silicon (c-Si), while maintaining appearing colors.
