Abstract: A solar cell includes: a semiconductor substrate of one conductivity type; a first semiconductor layer of the one conductivity type on the semiconductor substrate; a second semiconductor layer of the other conductivity type on the semiconductor substrate; an insulation layer between the first and second semiconductor layers in an area where the first and second semiconductor layers layer overlap each other; a first region where the first semiconductor layer is joined to the semiconductor substrate; a second region where the second semiconductor layer is joined to the semiconductor substrate; and a third region, which is a part of the first region, where the insulation layer is provided. The first region includes first finger sections and a first busbar section. The second region includes second finger sections and a second busbar section. At least a part of the first busbar section is provided in the third region.

Abstract: A solar cell includes: a semiconductor substrate having a light receiving surface and a back surface; a first semiconductor layer of the first conductivity type on the back surface; a second semiconductor layer of the second conductivity type on the back surface; a first electrode electrically connected to the first semiconductor layer; and an insulating layer for electrically insulating the first semiconductor layer and the second semiconductor layer from each other in a region in which an edge of the first semiconductor layer and an edge of second semiconductor layer overlap. The first electrode includes a first transparent electrode layer and a first collection electrode layer on the first transparent electrode layer. The first transparent electrode layer is separated into a primary electrode layer that is on the first semiconductor layer and a separated electrode layer that is on the second semiconductor layer in the region.
