  • Patent number: 9447514
    Abstract: A structure and method of making a thin-film solar cell is provided. A thin-film solar cell includes a substrate, absorber layer and a buffer layer. The absorber layer is deposited by a single-step bulk electrochemical process, or a multi-layer electrochemical process. The buffer layer is deposited by an electrochemical deposition process such as a multi-layer deposition or an atomic layer deposition. The absorber and buffer layers are non-toxic materials which can include sulfur incorporated during the deposition process or incorporated after deposition by an anneal step.
