Abstract
In a solar cell, there is provided a method of improving external appearance quality by lowering surface reflection and by making a change of a color tone at openings and portions between electrode patterns, resulting from integrating working, inconspicuous. In the solar cell, at the openings and the portions between the electrode patterns resulting from the integrating working, when seen from a light incident side, since the number of laminated films or the materials are different, colors in appearance become different among the respective regions. In the present invention, an insulating resin layer, a rear electrode layer, a sealing resin layer, and the like are colored by containing pigments or the like so that the colors thereof become similar to the color of a region of a structural portion occupying the great part of the solar cell. The coloring, together with the unevenness of the surface passivation layer, can make the change of the color tone at the openings and the portions between the electrode patterns resulting from the integrating working inconspicuous.
