An algorithm has been developed for calculating the parameters of plane-focusing optics intended for usage in concentrator modules for photovoltaic systems in solar energetics. The optics is specially adapted for modules based on crystalline silicon with certain sizes of a single photosensitive cell. The set of calculations of the geometric parameters of such optics was performed. Based on the calculations, test samples of «solar» lenses were formed using the diamond blade micro-cutting technique, and stamp matrices were also manufactured for replicating the lenses. A feature of focusing structures created by the diamond cutting technique is a discrete change in the refractive angles of micro-prismatic zones, resulting in the discreteness of the images formed in the focus. This is a main difference from Fresnel focusing optics with aspherical convex circular surfaces, when the angles of refraction change continuously. In the manufacture of such new devices by the diamond cutting method it is possible to obtain almost mirror working surfaces of a high optical quality. However, the size of such conical refracting zones should not be too large to reduce the discreteness of the formed images, so the new specified focusing microprisms are made from several totally identical prismatic elements. Methods for computer modeling of geometric parameters of lenses, as well as reproduction of the path of refracted rays, have been modernized. The obtained modeling results allowed optimizing the parameters of transforming optics and creating flat-focusing lenses, most suitable for use in solar modules. Test samples of the created lenses were examined using the laser diagnostics method. The results of the studies have confirmed the correspondence of the obtained parameters of actually manufactured lenses to the calculated data and the results of computer modeling. Fig.: 17.
