A sunlight concentrator for a photovoltaic generation system (1), the concentrator (2) having an optical axis (3) and a curved reflecting surface (2a) to concentrate, according to a concentrated beam (6, 7) of rays ideally focusing in a focus (F) lying on the optical axis (3), the sunlight that strikes, according to an incident beam (4, 5) of rays parallel to the optical axis (3), on the reflecting surface (2a), and in which the reflecting surface (2a) has a curvature generated by a movement of a generatrix (10) consisting of a branch of a curve described by a polynomial function of degree in the range between 2.1 and 1.9, but different from 2. |
