Abstract
A layer structure for a thin-film solar cell and production method are provided. The layer structure for the thin-film solar cell includes a photovoltaic absorber layer doped, at least in a region which borders a surface of the photovoltaic absorber layer, with at least one alkali metal. The layer structure has an oxidic passivating layer on the surface of the photovoltaic absorber layer, which is designed to protect the photovoltaic absorber layer from corrosion.

A layer structure for a thin-film solar cell, comprising
- a photovoltaic absorber layer doped, at least in a region bordering a surface of the photovoltaic absorber layer, with at least one alkali metal, and
- an oxidic passivating layer on the surface of the photovoltaic absorber layer, the oxidic passivating layer being designed to protect the photovoltaic absorber layer from corrosion.
A method for producing a layer structure for a thin-film solar cell, comprising the following steps:
- a. generating a photovoltaic absorber layer, doped, at least in a region bordering a surface of the photovoltaic absorber layer, with at least one alkali metal, on a substrate, and
- b. generating an oxidic passivating layer on the surface of the photovoltaic absorber layer, the oxidic passivating layer being designed to protect the photovoltaic absorber layer from corrosion.
