Silicon solar cells are metalized with thin rectangular-shape strips printed on the front and back sides of a solar photovoltaic cell. These metallic contacts are called busbars and have a significant purpose: they conduct the direct current generated by the solar photovoltaic cell.
The tab wire is brazed either manually or automatically to the solar cell busbar, which connects the individual cells in series with a low series resistance. The tab wire is also made from round copper wire, by a rolling process and is coated with a layer of solder to permit easy soldering.
These metallic contacts are called busbars and have a significant purpose: they conduct the direct current generated by the solar photovoltaic cell. Frequently, solar cell busbars are constructed from copper, coated with silver. The silver coating is necessary to enhance current conductivity (front side) as well as to lower oxidization (rear side).
The solar photovoltaic cells have to be connected in series which form rows, to obtain suitable voltages. The tab wire is brazed either manually or automatically to the solar cell busbar, which connects the individual cells in series with a low series resistance.
TECC-Wire is a low-temperature (< 200°C) non-soldering solar cell inter-connection technology. Basically, a multi-wire approach with very special wires. We see a very good electrical and mechanical contact both to SiN and TCO. The observed losses can be attributed to the fully manual application of the wires.
The most common solar cell design involves three busbars (3BB) printed onto the cell. Five busbars (5BB) cells are currently one of the leading trends in solar cell and module design.
Real-World Implementations Across Diverse Sectors
A single solar cell can have up to 8 dash lines, but this is still less material-consuming than a 3BB line solar cell. Please note: Every emerging busbar design trend has its own limitations. For example, the dash-line busbar …
