Abstract
The solar collector according to the invention comprises a membrane arrangement (41) having zones (70, 71, 72) with different spherical curvatures such that the concentrator membrane (42), which is covered with a reflecting layer, approximates a parabolic shape in an optimal way and therefore has an optimally small focal point region or focal line region
glass sheet, process of obtaining a glass sheet, use of the glass sheet, and photovoltaic cell, solar cell, or flat or parabolic mirror for the concentration of solar energy
