摘要

The present invention relates to the use of microporous, anionic, inorganic framework structures, in particular framework silicates or framework devices, in thin-film solar cells or modules, in particular based on a glass substrate layer, for taking up impurities from these thin-film solar cells or modules and for producing a semiconductor absorber layer provided with monovalent dopant cations a thin-film solar cell or module, in particular based on a glass substrate layer. The invention further relates to a photovoltaic thin-film solar cell containing, in particular in at least one back electrode layer, at least one contact layer and / or at least one semiconductor absorber layer, microporous anionic inorganic framework structures, in particular framework silicates or framework geranium. In this case, the semiconductor absorber layer is preferably doped, in particular in exchange with metal ions of the semiconductor absorber layer, with monovalent dopant cations, in particular alkali ions, originating from the framework structures. Furthermore, the invention relates to a thin-film solar module containing thin-film solar cells according to the invention. Finally, the invention relates to a method for producing thin-film solar cells and modules according to the invention.
