In this work we present the results of a study of model samples of solar collectors with an absorption material based on carbonized vegetable raw materials from apricot stones, rice husks and their combination with carbon nanotubes. These studies have shown the possibility and prospects of the use of carbon structures based on carbonized vegetable raw materials for the absorbing layers of solar collectors. Experimentally, on the basis of a comparative study of the absorption capacity of the coatings from carbonized rice husk, apricot stones, and their combination with the carbon nanotubes, it was found that the maximum absorption capacity was observed for a coating based on carbonized rice husks.
