Abstract
A solar cell includes a semiconductor substrate, a tunneling layer on one surface of the semiconductor substrate, a first conductive type area on the tunneling layer, a second conductive type area on the tunneling layer such that the second conductive type area is separated from the first conductive type area, and a barrier area interposed between the first conductive type area and the second conductive type area such that the barrier area separates the first conductive type area from the second conductive type area.
