Abstract
The seasonal behavior of one-dimensional periodic structure is validated. The structure has angular dependence of reflectivity that changes from high reflectivity for summer to low reflectivity for winter. Sunlight simulator is used for exposing the one-dimensional periodic structure and non-structured surface to measure the substrate temperature while changing the angle of incidence from 0 degree to 70 degree. As a result, maximum temperature difference of these structures is achieved where 1.2°C at an angle of incidence of 40 degree.
