Abstract
A method of fabricating a photovoltaic cell, and apparatus formed by the method, yields increased quantum efficiency. A back contact layer is formed above a substrate. An absorber layer is formed above the back contact layer. A buffer layer is formed above the absorber layer. A transparent conductive layer is formed above the buffer layer. A surface of the transparent conductive layer is treated with an acid to increase roughness of the surface.
