APPARATUS FOR THE CONVERSION OF SOLAR ENERGY INTO ELECTRIC POWER

摘要

Apparatus for the conversion of solar energy into electric power, which comprises a support frame (2); a solar radiation concentration device (3) mounted on said support frame (2); a device (4) for the spectral separation of the solar radiation beam (Rc) concentrated by the concentration device (3), such device (4) adapted to divide the concentrated solar radiation beam (Rc) into a first beam (6) and a second beam (7) having different spectra; and a first photovoltaic module (8) and a second photovoltaic module (9), susceptible to respectively receive the first beam (6) and the second beam (7) and comprising photovoltaic cells having maximum conversion efficiency respectively in the spectral region characteristic of the first beam (6) and in the spectral region characteristic of the second beam (7). The spectral separation device (4) comprises: a support structure (10) mounted on the support frame (2) or on the concentration device (3) and provided with a seat (1 1) arranged so as to interfere with the concentrated solar radiation beam (Rc); a dichroic filter (12) removably housed in the seat (11) and engaged with the support structure (10) by means of removable engagement means (13); and anchorage means (14) for retaining the first photovoltaic module (8) and the second photovoltaic module (9) mechanically fixed to the support structure (10) so as to respectively intercept the first transmitted beam (6) and the second reflected beam (7) from the dichroic filter (12).
