Abstract
A method of manufacturing thin-film solar cells that include a layer of copper indium selenide (CuInSe.sub.2) that is applied in one manufacturing step onto a substrate that includes a metal layer that defines an electrical back contact layer of the solar cell. A layer that contains an alkali metal, such as sodium, is formed on the cell structure before the CuInSe.sub.2 layer is applied.
