The present invention relates to a solar cell. The solar cell includes a substrate; a first electrode layer formed on the substrate; a middle connection layer which is formed on the first electrode layer and includes a first region and a third region; a light absorption layer which is formed on the third region of the middle connection layer; and a wire which is formed on the first region of the middle connection layer. The thickness of the first region of the middle connection layer is different from that of the third region of the middle connection layer. |
