  • Solar Cell Apparatus and Method for Manufacturing the Same
    Publication number: 20120273039
    Abstract: Disclosed are a solar cell apparatus and a method for manufacturing the same. The solar cell apparatus includes a substrate, a back electrode layer on the substrate, a light absorbing layer on the back electrode layer, and a front electrode layer on the light absorbing layer. An outer lateral side of the back electrode layer is aligned on a plane different from a plane of an outer lateral side of the front electrode layer. In the solar cell apparatus, short is prevented between the back and front electrode layers.
