A PHOTOVOLTAIC DEVICE WITH A METAL OXYSULFIDE 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 MS1-xOx window layer formed over the substrate structure, wherein M is an element from the group consisting of Zn, Sn, and In. Another embodiment is directed to a process for manufacturing a photovoltaic device including forming a MS1-xOx window layer over a substrate by at least one of sputtering, evaporation deposition, CVD, chemical bath deposition process and vapor transport deposition process, wherein M is an element from the group consisting of Zn, Sn, and In.
