Carbon-siliceous nanocomposites via the method of sol-gel technology for selective coatings of solar collectors

Abstract

It was developed the selective coating by new type for the solar heat collectors. It has been used the carbon-siliceous nanocomposite obtained via sol-gel technology method. The comparative investigations of the obtained coating and the sample of SunSelect firm (Germany) were carried out. The distinctive peculiarity is the preparation of the coating by a high cost technology of the vacuum evaporation. The independent measurements have been done under the irradiation of the natural solar flow of radiation and the simulator of the solar spectrum.
