<p>PROBLEM TO BE SOLVED: To provide a light condensing solarlight power generator having a high efficiency by suppressing a decrease in an output due to a resistance loss or a chromatic aberration without reducing a photodetecting amount even without enhancing a tracking accuracy or an assembling accuracy. SOLUTION: Since a local light condensing density is enhanced in the vicinity of a pair of bus bars 42 as compared with that of another region on a photodetecting surface 38 of a solar battery cell 36 via a secondary condenser lens 34, a substantial photodetecting area of the cell 36, is enlarged, and the area utility ratio is enhanced. Hence, the photodetecting amount is assured without enhancing the tracking accuracy or the assembling accuracy. Further, since problems due to a distribution diode effect or an ohmic contact disturbance in association with a current concentration are eliminated, the substantial resistance of a pectinated electrode 40 is reduced, and further a condensing density near the bus bar 42 is enhanced, a photocurrent of each wavelength can approach to each other, and hence the photodetecting amount is not reduced even without enhancing the tracking accuracy or the assembling accuracy, the decrease in the output due to the resistance loss or the chromatic aberration is suppressed, and the efficiency of the solar light power generation is enhanced.</p> |
