Kurzfassung englisch:
PV-modules with small rectangular solar cells from polycrystalline silicon were made in which the cell interconnections consist of overlapping the cells and placing contact strips in between. The lamination pressure bends the cells around the contact strips, which ensures good contact by "pressure-only" after the encapsulating material has hardened. Results are presented of rapid aging tests on small modules and of up to one year of outdoor experience with large modules of the 240 W class. In the latter, all cells are connected in series to obtain operating voltages around 120 V and currents around 2 A. Contact strips with coatings of SnPbAg, Ag, and pure Cu were investigated. The Ag-coated "pressure-only" contact strips performed as good as soldered cell interconnections.
