Abstract
Provided is a solar cell including a photoelectric conversion section having a first principal surface and a second principal surface, and a collecting electrode formed on the first principal surface of photoelectric conversion section. The photoelectric conversion section includes a semiconductor-stacked portion including a semiconductor junction, a first electrode layer which is a transparent electrode layer formed on the first principal surface side of the semiconductor-stacked portion, and a second electrode layer formed on the second principal surface side of the semiconductor-stacked portion. The collecting electrode includes a first electroconductive layer and a second electroconductive layer. In the manufacturing method, an insulating layer is formed on the first electrode layer, and the electrode layer exposed to the surface of the insulating layer-non-formed region is removed to eliminate a short circuit between the first and second electrode layers. The second electroconductive layer is formed by plating.
