A solar cell includes a first conductivity type semiconductor substrate, a second conductivity type semiconductor layer disposed at a first surface of the semiconductor substrate, a first electrode disposed on the semiconductor layer, a second electrode disposed on the first semiconductor substrate

A solar cell includes a first conductivity type semiconductor substrate, a second conductivity type semiconductor layer disposed at a first surface of the semiconductor substrate, a first electrode disposed on the semiconductor layer, a second electrode disposed on the first semiconductor substrate opposite the layer, a connection electrode disposed on the first surface f the semiconductor substrate insulated from the semiconductor layer, and an electrically conducting layer electrically connecting the second electrode and the connection electrode extending in the direction of the thickness of the semiconductor substrate. Since the first electrode and the connection electrode of the solar cell are both disposed on the first surface of the semiconductor substrate, the interconnection of a pair of adjacent solar cells is greatly simplified.
