Abstract
A solar cell includes a photoelectric conversion substrate, a first electrode on one surface of the substrate, a second electrode on the other surface of the substrate, and a third electrode on the other surface of the substrate. The third electrode extracts electric power from the second electrode, and overlaps the second electrode at the periphery in the in-plane direction of the photoelectric conversion substrate. The thickness of the second electrode is larger than that of the third electrode, and the difference between the thickness of the second electrode and that of the third electrode is not less than 10 micrometers and not more than 30 micrometers.
