First Claim
1. Process for manufacturing a solar cell foil provided with solar cells connected in series, which process comprises the following steps:
- providing a temporary substrate;
followed byapplying a transparent conductive oxide (TCO) layer on the temporary substrate;
followed byapplying a photovoltaic (PV) layer on the TCO layer;
followed byapplying a back electrode onto the PV layer;
followed bysimultaneously or sequentially in any order applying a conductive layer connection which connects the back electrode to the TCO layer, andproviding a groove in the back electrode down to the PV layer;
followed byproviding a permanent carrier;
followed byremoving the temporary substrate; and
followed byproviding a groove from a side of the TCO layer through the TCO layer through the PV layer down to the back electrode.

Abstract
The invention pertains to a method of manufacturing a photovoltaic foil provided with solar cells connected in series, which method comprises the following steps: a) providing a temporary substrate b) applying a transparent conductive oxide (TCO) c) applying a photovoltaic (PV) layer on the TCO d) if so desired, applying one or two insulating strips onto the PV layer e) applying a back electrode onto the PV layer and, if they are present, onto the insulating strips f) if so desired, repairing shunts in the back electrode g) providing a groove in the back electrode down to the PV layer, or if it is present, down to an insulating strip h) if so desired, providing a permanent carrier i) removing the temporary substrates j) providing a groove from the side of the side of the TCO through the TCO and, optionally, through the PV layer down to the back electrode, or if it is present, down to an insulating strip if so desired, applying an encapsulant onto the TCO layer, in which process a conductive connection through the PV layer is established (i) between steps f. and h, or (ii) between steps i. And k, or (iii) if one or two insulating strips are applied onto the PV layer in step d, between steps c. and e.
