A solar cell includes a substrate, a doped pattern, a contact layer, and an electrode. The substrate includes a first surface onto which sunlight is incident and a second surface facing the first surface. The doped pattern is formed on the second surface of the substrate and the contact layer is formed on the doped pattern. The electrode is formed on the contact layer and is electrically connected to the doped pattern. Accordingly, a contact resistance between the substrate and the electrode may be decreased, so that the doped pattern and the electrode may be uniformly formed and a power efficiency of the solar cell may be improved.
