Abstract
For producing a photovoltaic module (), the front electrode layer (), the semi-conductor layer () and the back electrode layer () are patterned by separating lines () to form series-connected cells (C, C, . . . C, C). The patterning of the front electrode layer () and of the semiconductor layer () is done with a laser () emitting infrared radiation. During patterning of the semiconductor layer () the power of the laser () is so reduced that the front electrode layer () is not damaged.
