NOVELTY - Making solar cell module involves providing a system made of a substrate (1) having an electrode layer (2) and an active layer (3); making in the system, a pair of a first interruption groove (4) in the electrode layer and active layer, and a second interconnection groove (5) in the active layer; inserting insulating compound (6) in interruption groove; and applying lift-off compound (7) on the active layer, at a position adjacent to the interconnection groove, on other side of the interconnection groove than the insulation groove, before, after or simultaneously with the inserting step.    USE - For making a solar cell module containing solar cells connected in series (claimed).    ADVANTAGE - The process produces the solar cell module with all the needed patterning in one process step. The patterning takes place when one of the electrodes and the active layer, is deposited on the substrate. The process is carried out in a fast and simple manner, as repositioning is not required in the process.    DETAILED DESCRIPTION - Making a solar cell module containing solar cells connected in series, involves providing a system made of at least one substrate (1) sequentially overlaid by a first electrode layer (2) and an active layer (3); making in the system, at least one pair of a first interruption groove (4) that provides an interrupt in the electrode layer and the active layer, and a second interconnection groove (5) through the active layer, such that the first and second grooves are positioned close to each other; inserting an insulating compound (6) into the first interruption groove; applying a lift-off compound (7) on the active layer, at a position adjacent to the second interconnection groove, on other side of the interconnection groove than the insulation groove, before, after or simultaneously with the insertion step of the insulating compound; applying a second electrode (8) on the active layer, the insulating compound and the lift-off compound; and removing the lift-off compound and the second electrode at a position, to obtain a groove (9) in the second electrode. The first and second grooves are preferably made by laser-scribing. The solar cell module includes the first electrode, the active layer and the second electrode; where at least one of the first and second electrodes is a transparent conductive oxide layer, and the other electrode can be a back electrode. The interrupt in the transparent conductive oxide layer is obtained through vitrification of the transparent conductive oxide. The lift-off compound is a dispersion of filler particles having a thickness of greater than 2 microns in a solution of a polymer and a solvent.
