In a photovoltaic generation system (1) provided with a concentrator (2) of sunlight having an optical axis (3) and a curved reflecting surface (2a) to concentrate, according to a concentrated beam (6, 7) of rays focusing in a focus (F) on the optical axis (3), the sunlight that strikes, according to an incident beam (13, 14) of rays parallel to the optical axis (3), on the reflecting surface (2a), a photovoltaic receiver (8) has a first photovoltaic converter (9) positioned between the concentrator (2) and the focus (F) so that to intercept the incident beam (4, 5) thus producing a shadow volume (7a) in the concentrated beam (6, 7), a second photovoltaic converter (15) positioned within the shadow volume (7a), and a glass plate (10a) interposed between the two converters (9, 15) and covered with a dichroic coating (10b) to separate the concentrated beam (6, 7) in a first and second beam (11, 12, 13, 14) having a different sunlight spectrum and so that the first beam (11, 12) is transmitted to the first converter (9) and the second beam (13, 14) is reflected towards the second converter (15). |
