A solar cell is disclosed. The solar cell includes a semiconductor substrate having a chamfer formed at an edge thereof and an electrode electrically connected to the semiconductor substrate through a conductivity type region. The electrode includes a plurality of finger lines extending in a first direction, and a plurality of bus bars positioned in a second direction and connecting the plurality of finger lines. The plurality of bus bars include a pair of first bus bars respectively positioned at opposite ends of the semiconductor substrate and separated in the first direction by a first width greater than a width of the chamfer, and a second bus bar positioned between the pair of first bus bars. The plurality of finger lines positioned in a first area between one end of the semiconductor substrate and one of the pair of first bus bars have different shapes from the plurality of finger lines positioned in a second area between the pair of first bus bars.
