Abstract
A solar cell includes a first conductive type semiconductor substrate in which a through hole is formed, a second conductive type impurity diffusion layer provided on one-surface side of the semiconductor substrate, a light-receiving surface electrode provided to be electrically connected to the impurity diffusion layer, a lead-out electrode led out to the other-surface side of the semiconductor substrate via the through hole and provided to be electrically connected to the light-receiving surface electrode, and a back-surface electrode electrically connected to the semiconductor substrate on the other-surface side of the semiconductor substrate and electrically separated from the lead-out electrode. The lead-out electrode contains a metal member inside the through hole and is electrically connected to the light-receiving surface electrode.
