Abstract
A method for post-treating an absorber layer for photoelectric conversion of incident light into electric current. The method includes providing a chalcogen-containing absorber layer on a carrier, applying a post-treatment layer on a surface of the absorber layer, wherein the post-treatment material is not a buffer or component of a buffer, and thermally diffusing the post-treatment material into the absorber layer. A method for producing a layer system for the production of thin-film solar cells is also described.

A method for post-treating an absorber layer for photoelectric conversion of incident light into electric current, comprising:
- providing a chalcogen-containing absorber layer on a carrier;
- applying a post-treatment layer on a surface of the absorber layer, wherein the post-treatment layer contains at least one post-treatment material selected from the group consisting of a metal chalcogenide, an oxygen compound of a metal chalcogenide, and a hydrogen-oxygen compound of a metal chalcogenide;
- and
- thermally diffusing the at least one post-treatment material into the absorber layer.
