According to the present invention there is provided a solar radiation band pass filter system for producing electrical current from concentrated solar radiation. The solar radiation is in the wavelength range W ranging from a wavelengths v1°v2. The range W comprises at least three sub-ranges: W1 including v1, W3 including v2, and W2 separating W1 and W3, and not including v1 and v2. The system comprises a beam splitter adapted for splitting the concentrated solar radiation into a first beam carrying radiation of sub-range W2 and directed in a first direction, and a second beam carrying radiation of sub-range W1 and W3 directed in a second direction. The system further comprises a first photovoltaic receiver adapted for producing electrical current from the first beam, and a second photovoltaic receiver adapted to produce electrical current from the second beam. |
