A method for manufacturing a solar cell includes forming an emitter layer on a first surface of a substrate, forming a back surface field layer on a second surface opposite the first surface of the substrate, forming a first anti-reflection layer on the emitter layer, forming a second anti-reflection layer on the back surface field layer, and forming a plurality of first electrodes each including a first metal seed layer and a first conductive layer on a plurality of first contact regions of the first anti-reflection film and a plurality of second electrodes each including a second metal seed layer and a second conductive layer on a plurality of second contact regions of the second anti-reflection film, the plurality of first contact regions being partially formed at the first anti-reflection layer and each having a first width.
