This invention was made with Government support under ZAX-4-33628-05 awarded by the United States Department of Energy under the photovoltaic (PV) Manufacturing Research and Development (R&D) Program, which is administered by the National Renewable Energy Laboratory. The Government has certain rights in the invention.
1. A cell connection assembly for a photovoltaic module, the cell connection assembly comprising:
a cell connection piece, comprising:
a plurality of bus tabs unitarily formed with the interconnect bus, wherein the plurality of bus tabs extend from only a single side of the interconnect bus; and
a terminal bus bar coupled with the interconnect bus of the cell connection piece, the terminal bus bar coupled to the interconnect bus at a solder joint, the terminal bus bar including a first portion defining a non-orthogonal, curvilinear shape and a second portion defining either a tapered shape or a hole to facilitate coupling of the second portion of the terminal bus bar to a terminal of a junction box of the photovoltaic module.
2. The apparatus of claim 1, wherein the interconnect bus has a continuously variable width along a length of the interconnect bus.
3. The apparatus of claim 1, wherein the interconnect bus has a step-wise variable width along a length of the interconnect bus.
4. The apparatus of claim 1, wherein the interconnect bus comprises an extension at an end of the interconnect bus, the solder joint formed at the extension.
5. The apparatus of claim 1, wherein the interconnect bus comprises an expansion joint to accommodate thermal expansion of the photovoltaic module, wherein the expansion joint is unitarily formed with the cell connection piece.
6. The apparatus of claim 1, wherein the interconnect bus comprises a plurality of notches to accommodate a second plurality of bus tabs of a second cell connection piece in a fabrication process of the cell connection pieces.
7. The apparatus of claim 1, wherein the cell connection piece is formed from a sheet of conductive material.
