A solar cell including a semiconductor substrate of a first conductive type; a first region of a second conductive type provided on a surface of the substrate; and a bypass function region including a second region of a second conductive type provided on the surface of the substrate and spaced a predetermined distance from the first region, and a third region for setting the substrate and the second region at the same potential; wherein when a reverse voltage is applied between the substrate and the first region, the bypass function region forms a bypass circuit between the substrate and the first region using a depletion layer formed inside the substrate by the reverse voltage. |
