发明名称 Annealing processes for photovoltaics
摘要 Processes for making a solar cell by depositing various layers of components on a substrate and converting the components into a thin film photovoltaic absorber material. Processes of this disclosure can be used to control the stoichiometry of metal atoms in making a solar cell for targeting a particular concentration and providing a gradient of metal atom concentration. A selenium layer can be used in annealing a thin film photovoltaic absorber material.

主权项 1. A process for making a thin film solar cell on a substrate comprising: (a) providing a thin film coated on a first substrate; (b) depositing a selenium layer onto a second substrate, wherein the selenium layer is formed by depositing elemental selenium or a selenium-containing compound; (c) arranging the first and second substrates so that the thin film is parallel to, and facing the selenium layer, wherein the thin film and the selenium layer are spaced apart, and wherein the space between the thin film and the selenium layer is occupied by vacuum or a gas; and (d) heating the first and second substrates.
