METHOD FOR MAKING SOLAR SUB-CELLS FROM A SOLAR CELL

摘要

The invention pertains to a method for making a solar cell module comprising solar cells connected in series, comprising the steps of : a) making in a system composed of a substrate-overlaid by a first electrode layer, itself overlaid by an active layer, a first, interruption, groove providing an interrupt in the front electrode and the active layer and a second, interconnection, groove through the active layer, the first and second grooves being positioned close to each other; b) inserting an insulating compound into the interruption groove; c) applying a lift-off compound onto the active layer at a position adjacent to the interconnection groove on the other side of the interconnection groove than the insulation groove; d) applying the second electrode; e) removing the lift-off compound and the overlaying second electrode at that position to obtain a groove in the second electrode.
