Abstract:
The solar cell includes a plurality of light-receiving-side finger electrodes on a light-receiving surface of a photoelectric conversion section having a semiconductor junction. The light-receiving surface of the photoelectric conversion section is covered with a first insulating layer. Each light-receiving-side finger electrodes include: a first metal seed layer provided between the photoelectric conversion section and the first insulating layer; and a first plating metal layer being conduction with the first metal seed layer through openings formed in the first insulating layer. The solar cell includes an isolated plating metal layer pieces contacting neither the light-receiving-side finger electrodes nor the back-side finger electrodes. On the surface of the first insulating layer, an isolated plating metal crowded region is present in a form of a band-shape extending parallel to an extending direction of the light-receiving-side finger electrodes.
