Abstract
Discussed is a solar cell including a semiconductor substrate, a first conductive type region formed on a surface of the semiconductor substrate, a second conductive type region formed on the other surface of the semiconductor substrate, the second conductive type region being spaced from an edge of the semiconductor substrate and having a conductive type different from that of the first conductive type region, an isolation portion formed at a perimeter of the second conductive type region on the other surface of the semiconductor substrate, a first electrode connected to the first conductive type region, and a second electrode connected to the second conductive type region, wherein the second conductive type region has a boundary portion in a part adjacent to the isolation portion, and in which a doping concentration or a junction depth varies over a width of the boundary portion.
