405 Optimum Design of Optical Multilayer Coatings on Window Pane for Solar Energy Control : Study on the Structure of Multilayer Coatings for Plural Incident Angles

Abstract

Optical multilayer coatings are able to control the solar energy by means of the multiple interference of light. In this paper, the optimum structure of the multilayer coatings is designed to achieve the target spectrum characteristic for using window pane both as summer season and winter season. Three cases of the structure of the window pane with a certain number of thin film layers - in case of the films are coated on the front side, the both sides or the back side are examined. The plural incident angles of sunlight is considered. The results of optimum design results and comparing the three cases in some patterns are shown.
