<p>The present invention improves efficiency of a back-junction solar cell. The solar cell has, on a substrate (11), a light receiving surface that receives solar light, and a rear surface that is provided on the reverse side of the light receiving surface, and is provided with electrode sections (16, 17) formed on the rear surface of the substrate (11). The electrode sections has: a plurality of n-type narrow line electrodes (16f) formed on the rear surface; a plurality of p-type narrow line electrodes (17f) formed adjacent to the n-type narrow line electrodes (16f); an n-type bus bar electrode (16b) that connects the n-type narrow line electrodes (16f) to each other; and a p-type bus bar electrode (17b) that connects the p-type narrow line electrodes (17f) to each other. In each of the electrode end portions of the narrow line electrodes (16f, 17f), a portion where two sides intersect is formed in an arc shape.</p> |
