Abstract:
A photovoltaic module comprising:a first and a second photovoltaic cell, each cell being disposed on a respective substrate, and each cell comprising a substrate electrode, a top electrode, and a photovoltaic semiconductor body disposed therebetween in electrical communication with said substrate electrode and said top electrode, each cell further including a plurality of current collecting grid wires disposed atop said top electrode, in electrical contact therewith; wherein, the grid wires of said first cell are in electrical communication with a current collecting bus bar; and the grid wires of said second cell extend beyond said second solar cell onto, and establish electrical contact with, the substrate electrode of said first cell so as to establish an unbroken current path therebetween; whereby, a series electrical connection is established between said first cell and said second cell; and wherein said first and second cells are disposed in a shingled relationship so that a portion of the substrate of one of said first and second cells overlies a portion of the other of said first and second cells.
