Abstract
A solar cell includes a silicon substrate, an aluminum electrode that collects electricity from the rear surface of the silicon substrate, and a silver electrode that extracts output from the aluminum electrode. The aluminum electrode includes an opening formed on the rear surface of the silicon substrate. On a side of the opening is formed a notch that recesses parallel to the direction in which principal stress acts in a plane of the silicon substrate. The silver electrode covers at least the opening and the notch of the aluminum electrode.
