A structure including a barrier layer adjacent to a substrate, a transparent conductive oxide layer adjacent to the barrier layer, and a buffer layer adjacent to the transparent conductive oxide layer. In the structure, the barrier layer includes a silicon aluminum oxide, the transparent conductive oxide layer includes cadmium and tin and the buffer layer comprises tin oxide. A photovoltaic device that includes the described structure along with a semiconductor window layer adjacent to the buffer layer and a semiconductor absorber layer adjacent to the semiconductor window layer. Methods of manufacturing a photovoltaic structure are also disclosed, as well as a sputter target for use in the manufacture of a photovoltaic device and methods of manufacturing the same. |
