摘要： A radiative cooling device, and a method of manufacturing the same, includes a reflective layer disposed on a substrate and responsible for reflecting sunlight having wavelengths corresponding to ultraviolet, visible, and near-infrared regions; and a radiative cooling layer disposed on the reflective layer and responsible for absorbing sunlight having a wavelength corresponding to a mid-infrared region and emitting the sunlight as heat, wherein the radiative cooling layer includes a first radiation layer including an uneven pattern; and a second radiation layer disposed on the first radiation layer and having a refractive index different from that of the first radiation layer.
