Abstract
A solar cell includes a substrate of a first conductive type, an emitter region of a second conductive type opposite the first conductive type and which forms a p-n junction along with the substrate, an anti-reflection layer positioned on the emitter region, a front electrode part electrically connected to the emitter region, and a back electrode part electrically connected to the substrate. The substrate includes a first area formed of single crystal silicon and a second area formed of polycrystalline silicon. A thickness of the anti-reflection layer positioned in the first area is less than a thickness of the anti-reflection layer positioned in the second area.
