    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.
