Title: Article with buffer layer

Abstract

An article, for example a solar cell, includes a first substrate having a first surface and a second surface. An underlayer is located over the second surface. A first conductive layer is located over the underlayer. An overlayer is located over the first conductive layer. A semiconductor layer is located over the conductive oxide layer. A second conductive layer is located over the semiconductor layer. The first conductive layer can include a conductive oxide and at least one dopant selected from the group consisting of tungsten, molybdenum, niobium, and/or fluorine. The overlayer can include a buffer layer having tin oxide and at least one of zinc, indium, gallium, and magnesium.
