Abstract
A solar cell of the present invention includes a collecting electrode extending in one direction on a first principal surface of a photoelectric conversion section. The collecting electrode includes first and second electroconductive layers in this order from the photoelectric conversion section side, and further includes an insulating layer provided with openings between the electroconductive layers. The first electroconductive layer is covered with the insulating layer, and the second electroconductive layer is partially in conduction with the first electroconductive layer through the openings of the insulating layer. The first electroconductive layer has non-central portions within a range from both ends of the first electroconductive layer, and a central portion between the two non-central portions, in a direction orthogonal to an extending direction of the first electroconductive layer. A density of openings at the central portion is higher than a density of openings at the non-central portion.
