Abstract
An energy conversion efficiency of a solar cell, as well as a quality of a lens concentrator, are of great importance in modern photovoltaic (PV) modules. Lens concentrators must provide maximum energy through to solar cell and must be resistant against water and water vapor. To solve the first task we calculated and covered the outer and the inner surfaces of the lens with the following antireflective layers – SiO2 with thickness of 85 nm (n = 1.47), ZrO2 with thickness of 63 nm (n = 1.98), and SiO2 with thickness of 85vnm (n =v1.47) – that achieved considerable increase (some wavelengths up to 10%) in energy of light passing through for wavelengths of 0.6 – 0.8 μm range. Multilayer antireflective coated polymer lens with high adhesion was proposed. Good adhesion was achieved by the formation of solid layer on the surface of the lens by means of sinking and removing the lens in the liquid polysiloxanevarnish basin before layering with antireflective coatings. To increase aquabhopy, the fluoroplast layer with thickness of 20 – 30 nm was formed above the antireflective layer of the concentrator. Aquaphoby has considerably increased when adding this layer. That has been confirmed when tested it in natural moistening, also measuring the edge angle moisture that has increased for its part in about 80°.
