- Abstract
Optical and radiative properties of glazing materials are primary imputes for determination of the radiative cooling performance. In this paper, SiO2 shield for radiative cooling was designed and fabricated using the copper as a metal layer. The thin layer (0.2) on SiO2 substrate (2mm) was produced using a sputtering technique. Spectral specular reflectance and transmittance of the film were measured accurately for 0.3 to 20 using an automated spectroradiometric system of high resolution. This class of coating is characterized by high solar band reflectance and high IR band emittance; so cooling to low temperature is possible with Cu/SiO2 system which is good reflectance in the visible range and are strongly emitting in 8- 13 band.
