In one aspect of the present invention, a transparent electrode, is presented. The transparent electrode includes a substrate and a transparent layer disposed on the substrate. The transparent layer includes (a) a first region including cadmium tin oxide; (b) a second region including tin and oxygen; and (c) a transition region including cadmium, tin, and oxygen interposed between the first region and the second region, wherein an atomic ratio of cadmium to tin in the transition region varies across a thickness of the transition region. The second region further has an electrical resistivity greater than an electrical resistivity of the first region. A photovoltaic device, a photovoltaic module, a method of making is also presented. |
