Abstract

For the manufacture of a photovoltaic module (1), there are attached to a transparent substrate (2) a transparent front electrode layer (3), a semiconductor layer (4) and a rear electrode layer (5) which, for forming cells (C1, C2, . . . , Cn, Cn+1) connected in series, are structured by dividing lines (6, 7, 8). A water-soluble detachment mass (12) is applied using an inkjet printer (15) to the regions of the semiconductor layer (4) at which the dividing lines (8) are to be formed in the rear electrode layer (5), whereon the rear electrode layer (5) is attached. The detachment mass (12), with the regions attached thereto of the rear electrode layer (5), is removed using a water jet (13) while forming the dividing lines (8) in the rear electrode layer (5).
