Abstract
A solar cell includes a substrate, an emitter region which is positioned at the substrate and having a first sheet resistance, a first highly doped region which is positioned at the substrate and having a second sheet resistance less than the first sheet resistance, a first electrode positioned at the substrate and connected to the emitter region and the first highly doped region, and a second electrode positioned at the substrate and connected to the substrate, wherein the first highly doped region crosses the first electrode and is connected to the first electrode, an upper surface of the first highly doped region is projected from an upper surface of the emitter region toward a light incident surface of the substrate, and a lower surface of the first highly doped region has the same height as a lower surface of the emitter region.
