PHOTOVOLTAIC DEVICE WITH A ZINC MAGNESIUM OXIDE WINDOW LAYER

摘要

Methods and devices are described for a photovoltaic device and substrate structure. In one embodiment, a photovoltaic device includes a substrate structure and a CdTe absorber layer, the substrate structure including a Zn_1-xMg_xO window layer and a low conductivity buffer layer. Another embodiment is directed to a process for manufacturing a photovoltaic device including forming a Zn_1-xMg_xO window layer over a substrate by at least one of sputtering, evaporation deposition, CVD, chemical bath deposition process and vapor transport deposition process. The process including forming a CdTe absorber layer above the Zn_1-xMg_xO window layer.
