Abstract
A solar cell includes: a first-conductivity-type semiconductor substrate that includes an impurity diffusion layer on one surface side, which is a light receiving surface side, the impurity diffusion layer having a second-conductivity-type impurity element diffused therein; a plurality of linear light-receiving-surface-side electrodes that are a paste electrode that has a multi-layered structure, is formed by multi-layer printing of an electrode material paste on the one surface side, and is electrically connected to the impurity diffusion layer and that extend in parallel in a specific direction in a plane direction of the semiconductor substrate; and a back-surface-side electrode that is formed on another surface side of the semiconductor substrate. In the light-receiving-surface-side electrodes, the light-receiving-surface-side electrodes get smaller in width as they get closer in a width direction of the light-receiving-surface-side electrodes to a specific reference position.
