COMPARATIVE INVESTIGATION OF THE EFFICIENCY OF ABSORPTION OF SOLAR ENERGY BY CARBON COMPOSITE MATERIALS

This paper presents the results of research on the effi ciency of absorption of solar energy by various carbon materials (soot, carbonized apricot pits and rice husks, and carbon nanotubes in the form of a ″forest″), as well as by composites based on them with inclusions of metal oxide nanoparticles. An analysis of the effi ciency of absorption of solar energy by various carbon materials has demonstrated the advantage of the carbon material from carbonized apricot pits. The results of the comparative investigation of the absorptivity of apricot pits with that of the coating of a production prototype of solar collector are presented.
