Anti-reflective coatings for solar power optical lens concentrators of different geometric shapes

The paper presents studies related to the use of anti-reflective coatings in lens concentrators of solar energy and determining the dependence of its efficiency on the geometric shape of the lens concentrator. According to the preliminary results of the experiment, it was determined that the efficiency of the anti-reflective layer of the concentrator lens of the photoelectric converter depends on the shape of the surface on which it is laid to receive solar radiation energy. The maximum effect is obtained when it is laid on a flat surface. Which leads to the conclusion that to create a concentrator with an anti-reflective layer, it is appropriate to use a flat convex lens.
