The invention pertains to a process for manufacturing a solar cell foil comprising the steps of: providing an etchable temporary substrate, applying a front electrode of a transparent conductive oxide (TCO) onto the temporary substrate, applying a photovoltaic layer onto the TCO layer, applying a back electrode layer, applying a permanent carrier, ensuring that the front electrode and the back electrode are electrically connected in an interconnect to establish a series connection, the front and the back electrode each being interrupted by front and back groove, respectively, at different sides of the interconnect, in any one of the preceding steps providing an etch resist on the non-TCO side of the temporary substrate at least at the location of the interconnect, and at least not at the entire location of the front groove, selectively removing the temporary substrate where it is not covered with etch resist. The process of the invention provides a cap of a protective material on the interconnect, leading to a solar cell foil with improved properties. |
