Abstract
A solar cell module includes a first isolation groove for separating the first electrode layer; a second isolation groove for separating each of the first semiconductor layer, the transparent conductive layer, and the second semiconductor layer; and a third isolation groove formed in a position opposite from the first isolation groove across the second isolation groove and for separating each of the second electrode layer, the second semiconductor layer, the transparent conductive layer, and the first semiconductor layer. The second electrode layer includes: a first conductive layer formed on the first semiconductor layer constituting a bottom surface of the second isolation groove, on an inner wall of the second isolation groove, and on the second semiconductor layer; and a second conductive layer formed on the first conductive layer. A resistivity of the first conductive layer is higher than a resistivity of the second conductive layer, and the first conductive layer is filled on the first electrode layer constituting the bottom surface of the second isolation groove, up to at least a position of an interface between the transparent conductive layer and the second conductive layer.
