Solar cell, method for manufacturing same and solar cell module

A solar cell comprising:

• a photoelectric conversion section including a semiconductor junction having a light-receiving surface and a back surface opposite the light-receiving surface;
• a plurality of light-receiving-side finger electrodes on the light-receiving surface of the photoelectric conversion section;
• a plurality of back-side finger electrodes on the back surface of the photoelectric conversion section;
• a first insulating layer over the light-receiving surface of the photoelectric conversion section;
• and
• a plurality of first isolated plating metal layer pieces over the first insulating layer, the first isolated plating metal layer pieces being free from having an electrical coupling with the light-receiving-side finger electrodes and the back-side finger electrodes, wherein
• the light-receiving-side finger electrodes of the plurality of light-receiving-side finger electrodes each include:
• a first metal seed layer between the photoelectric conversion section and the first insulating layer;
• and
• a first plating metal layer over the first insulating layer, the first plating metal layer being coupled with the first metal seed layer by way of openings in the first insulating layer,
• the first isolated plating metal layer pieces are distributed in a first isolated plating metal crowded region over the first insulating layer having an area density of first isolated plating metal layer pieces included in the first isolated plating metal crowded region that is two times or more than an average area density of first isolated plating metal layer pieces over an entirety of a region over the first insulating layer free from having the light-receiving-side finger electrodes, and
• the first isolated plating metal crowded region extends along the light-receiving-side finger electrodes.
