<p>PROBLEM TO BE SOLVED: To provide a concentrating solar cell module, in which sunlight is condensed on a photovoltaic element without irregularities in the quantity of light, without chromatic aberrations and with satisfactory efficiency and which is especially small and low-cost in the module, which is provided with a primary optical system comprising a rectangular incident face and a secondary optical system, comprising a rectangular emission face, and to provide a concentrating photovoltaic power generation system which is constituted of the module and a tracking device. SOLUTION: The concentrating solar cell module is provided with the primary optical system 408, comprising the rectangular incident face and the secondary optical system 108, in which the sunlight collected by the system 408 is nearly fully incident from the incident face and in which the sunlight is totally reflected on the side face, so as to be emitted from the emission face. The system 108 is constituted of a transparent material, which is composed of a smooth-side- face, solid and uniform material, and it comprises the rectangular emission face 203. At least the photovoltaic element 204 is provided, immediately after the emission face 203.</p> |
