Abstract
A method of fabricating a solar cell includes forming a front contact layer over a substrate, and the front contact layer is optically transparent at specified wavelengths and electrically conductive. A first scribed area is scribed through the front contact layer to expose a portion of the substrate. A buffer layer doped with an n-type dopant is formed over the front contact layer and the first scribed area. An absorber layer doped with a p-type dopant is formed over the buffer layer. A back contact layer that is electrically conductive is formed over the absorber layer.
