Patent ID: 8759664

Claim:
A thin film photovoltaic module, comprising: first and second thin film photovoltaic cells, each cell having a top surface and a bottom surface; and an electrical conductor having a trailing portion including a first part extending longitudinally across the first cell and a second part extending transversely toward the second cell, and a leading portion extending longitudinally along the second cell, the first part of the trailing portion contacting the top surface of the first cell, the second part of the trailing portion disposed out of physical contact with each cell, and the leading portion wrapping around into contact with the bottom surface of the second cell to form an electrical series connection between the first and second cells; wherein the leading portion includes a first unfolded part, a second part that spans a fold, and a third part folded into direct contact with the first unfolded part to provide redundant contact to prevent the fold from becoming a failure point.
