<P>PROBLEM TO BE SOLVED: To provide a solar cell capable of improving a photocurrent without being controlled by the lowest photocurrent within photocurrents generated in a photoelectric conversion layer. Ž<P>SOLUTION: This solar cell is provided with: a plurality of cells 2 formed on the upper surface of a translucent insulation substrate 1, and each having a wide-band gap photoelectric conversion layer 12; and a plurality of tandem cells 3 formed on the lower surface of the translucent insulation substrate 1, and each having a middle-band gap photoelectric conversion layer 22 having an optical band gap different from that of the wide-band gap photoelectric conversion layer 12. The cell 2 and the tandem cell 3 facing each other interposing the translucent insulation substrate 1 constitute a unit 4. The wide-band gap photoelectric conversion layer 12 and the middle-band gap photoelectric conversion layer 22 of the unit 4 are electrically connected in parallel to each other through a through-hole 5 formed on the translucent insulation board 1. The photoelectric conversion layers 12 and the photoelectric conversion layers 22 of the units 4 adjacent to each other are electrically connected to each other. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
