摘要: A solar cell includes a silicon semiconductor substrate including a plurality of concave portions formed at a first surface thereof; an emitter layer formed at the first surface of the silicon semiconductor substrate having the plurality of concave portions; an antireflection layer formed on the emitter layer; and a front electrode layer connected to the emitter layer by penetrating through the antireflection layer. The front electrode layer is formed on a flat surface between the plurality of concave portions and has a finger matrix shape. Accordingly, an area of the concave portions effectively absorbing sun light can increase, and the reduction of fill factor can be reduced or prevented by a short horizontal migration length of electrons.

摘要: 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.

摘要: A solar cell and a method for manufacturing the solar cell are discussed. The solar cell includes a substrate, an emitter layer formed at an incident surface of the substrate, a first electrode part connected to the emitter layer, and a textured surface positioned on the incident surface of the substrate, at which the emitter layer is formed. The textured surface includes a plurality of depressions. A surface of an area of the substrate, on which the first electrode part is formed, is a flat surface not including the plurality of depressions.
