A method of manufacturing a solar concentrator, solar concentrator, solar module and method for generating electrical energy

A method of manufacturing a solar concentrator (1) made of a transparent material, said solar concentrator (1) a light-coupling surface (2), a convex light outcoupling surface (3) and a between the light-coupling surface (2) and the convex light outcoupling surface (3) arranged in the direction the light output surface (3) tapered light guide part (4), and wherein for forming the light-coupling surface (2) and at least a second mold (10) having a concave part for forming the convex light outcoupling surface (the transparent material between a first mold (14) 3) for solar concentrator (1) is pressed blank, wherein the transparent material (in the second mold by means of an underpressure 10) is pulled.
