PROBLEM TO BE SOLVED: To provide a condensation type solar battery that suppresses rate controlling in conversion efficiency by cells for a short wavelength band to achieve high efficiency.SOLUTION: A condensation type solar cell 100A includes: a condensing element 102; a first photoelectric conversion cell 110 that is arranged on a light incident surface of the condensing element 102, a light emission surface of the condensing element 102, or on the depth side of a light incident path with respect to the condensing element 102 and has a first band gap; a second photoelectric conversion cell 120 that is arranged on the depth side of the light incident path with respect to the first photoelectric conversion cell 110, has a second band gap smaller than the first band gap, and on which light condensed by the condensing element 102 is made incident; a first output circuit that outputs a first output current to be output from the first photoelectric conversion cell 110; and a second output circuit that is constituted independently of the first output circuit and outputs a second output current to be output from the second photoelectric conversion cell.SELECTED DRAWING: Figure 2 |
