Abstract
A bus bar for a silicon solar cell. The bus bar is a strip of electrically conductive material with a plurality of protrusions extending from at least one side of the bus bar.
Claims20
A pattern of electrically conductive material printed on a silicon solar cell comprising:
- at least one bus bar and a plurality of finger lines the bus bar and the finger lines made of electrically conductive material and deposited in two deposition processes, wherein
- the bus bar is a strip of electrically conductive material with a plurality of protrusions extending from at least one side of the strip, the strip includes a substantially flat surface configured to receive a tabbing ribbon of about the same or smaller width than that of the strip;
- and
- the finger lines overlap at least at one end with the protrusions.
1 more element
A solar cell comprising a substrate with at least one bus bar including a plurality of protrusions extending from at least one side of the bus bar and at least one segmented finger line;
- and
- wherein the at least one segmented finger line is deposited on the substrate in a deposition stage separate from the deposition stage at which the bus bar is deposited.
A method of printing electric current conductors on a surface of a silicon solar cell, comprising:
- providing at least one silicon solar cell;
- printing on light receiving surface of the silicon solar cell at least one segmented finger line configured to collect current from the silicon solar cell;
- and
- printing on light receiving surface of the silicon solar cell at least one bus bar with at least one protrusion extending from at least one side of the bus bar;
- and
- wherein at least one bus bar includes a surface configured to receive a tabbing ribbon and wherein the surface configured to receive a tabbing ribbon is substantially a flat surface.
