Abstract
A solar cell can include a silicon substrate; a tunnel layer disposed on a first surface of the silicon substrate, the tunnel layer including a dielectric material; a polycrystalline silicon layer disposed on the tunnel layer; a dielectric layer disposed on the polycrystalline silicon layer; and an electrode penetrating through the dielectric layer and directly contacting with the polycrystalline silicon layer, wherein the polycrystalline silicon layer includes a metal crystal region positioned at a region where the polycrystalline silicon layer contacts the electrode, and wherein the metal crystal region includes a plurality of metal crystals, the plurality of metal crystals including a metal material same as a metal material included in the electrode.
