Abstract: A thin film photovoltaic cell and method for forming the same. The thin film photovoltaic cell includes a first electrode layer formed on a substrate. An absorber layer of a first dopant-type is formed on the first electrode layer. The absorber layer has an opening extending partially into the absorber layer from a top surface of the absorber layer. The opening has side walls and a bottom surface. A buffer layer of a second dopant type is formed on the top surface of the absorber layer, the side walls of the opening and the bottom surface of the opening A second electrode layer is formed on the buffer layer.

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.

Abstract: A thin film solar cell and process for forming the same. The solar cell includes a bottom electrode layer, semiconductor light absorbing layer, top electrode layer, and a protective moisture barrier layer. In some embodiments, the barrier layer is formed of a water-insoluble material. The barrier layer helps protect the top electrode layer from exposure and damage caused by water and oxygen.
