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.
Claims14
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 substantially flat surface made of electrically conductive material configured to receive a tabbing ribbon of about the same width than that of the strip with a plurality of protrusions extending from at least one side of the strip beyond the tabbing ribbon;
- and
- the finger lines are printed such that they overlap at least at one end of the protrusions but do not continue under the tabbing ribbon.
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.
