Abstract

Disclosed herein are devices, systems, and methods for processing a solar cell precursor. The processing may include forming a transparent, electrically conductive first layer over the solar cell precursor. The processing may also include forming a transparent, electrically conductive second layer over the solar cell precursor, preferably in physical contact with the first layer. The first layer may comprise at least indium, zinc, and oxygen and the second layer may comprise oxygen and a greater proportion of indium than the first layer.
