Abstract

This solar module in integrated thin-film technology consists of a number of solar cells 11, 12, 13, 14 tandem mounted and series-connected on common substrate 1 and a number of diodes 21, 22, 23, 24 disposed parallel and adjacent thereto. Overlap zones 10, 20 are formed by a projecting edge area of electrode layer 2, 4 of a solar cell or diode engaging a recess in the corresponding electrode layer of the adjacent diode or solar cell. Each diode is connected in the reverse direction with the adjacent solar cell in at least two overlap zones, i.e. front electrode layer 2 of the diode with back electrode layer 4 of the solar cell in at least one of said overlap zones 10, and back electrode layer 4 of the diode with front electrode layer 2 of the solar cell in at least one other overlap zone 20.
