Abstract
A photovoltaic module includes at least a first and a second photovoltaic cell each having a substrate electrode, a top electrode and a photovoltaic semiconductor body disposed therebetween in electrical communication with the substrate electrode and the top electrode. Each cell includes a plurality of current collecting grid wires disposed atop the top electrode in electrical contact therewith. The grid wires of the first cell are in electrical communication with a current collecting bus bar and the grid wires of the second cell extend onto the first cell so as to establish an unbroken current path therebetween. The grid wires of the second cell may establish electrical communication with the substrate electrode of the first cell, in which case a series connection therebetween is established. Alternatively, the grid wires of the second cell may establish electrical communication with the top electrode of the first cell so as to create a parallel electrical connection therebetween. Also disclosed are methods for manufacturing the modules.
