According to an embodiment of the present invention, a solar cell includes a substrate; a backside electrode layer arranged on the substrate; a light absorption layer arranged on the backside electrode layer; a buffer layer arranged on the light absorption layer; and a through groove penetrating the buffer layer and the light absorption layer. A metal layer is arranged on the backside electrode layer exposed by the through groove. According to the embodiment of the present, a method for fabricating a solar cell includes a step for forming a backside electrode layer on a substrate; a step for forming a light absorption layer on the backside electrode layer; a step for forming a buffer layer on the light absorption layer; a step for forming a through groove penetrating the light absorption layer and the buffer layer; and a step for forming a metal layer formed on the backside electrode layer exposed by the through groove. |
