摘要：
Methods and devices are described for a photovoltaic device. The photovoltaic device includes a glass substrate, a semiconductor absorber layer formed over the glass substrate, a metal back contact layer formed over the semiconductor absorber layer, and a p-type back contact buffer layer formed from one of MnTe, Cd1-xMnxTe, and SnTe, the buffer layer disposed between the semiconductor absorber layer and the metal back contact layer.
