<p>The invention pertains to a process for manufacturing a thin film solar cell sheet provided with a plurality of solar cells connected in series which comprises the following steps: a) providing a temporary substrate; b) optionally providing a diffusion barrier layer; c) applying a transparent conductive oxide (TCO); d) applying a photovoltaic (PV) layer onto the TCO; e) providing a groove (1) through the PV layer and, if so desired, through the TCO; f) applying a back electrode onto the PV layer and in groove (1) and; when groove (1) has been provided through the TCO, if necessary providing a groove (2) in the back electrode inside groove (1) down to the temporary substrate in such a way that on one side of groove (2) the TCO and the back electrode are not interconnected, and when groove (1) has not been provided through the TCO, providing a groove (2a) through the back electrode down to the PV layer next to groove (1); g) applying a non-conductive material in grooves (1 and 2) or (2a), optionally combined with or followed by the application of a permanent substrate; h) removing the temporary substrate; i) providing a groove (3) from the TCO side through the TCO and, if so desired, through the PV layer outside groove (1) on the side of groove (1) opposite from groove (2) or (2a); j) when groove (1) has been provided through the TCO, establishing a conductive connection between the TCO on the side of groove (2) where the TCO and the back electrode are not interconnected and the back electrode on the opposite side of groove (2); k) applying an insulating material in groove (3) and, if so desired, simultaneously or successively over the top of the thin film solar cell sheet.</p> |
