About Tabbing Ribbon & Bus bar Ribbon
PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.
1. Tabbing Ribbon
Tabbing Ribbon commonly connects the positive and negative sides of the cells in series.
2. Bus bar Ribbon
Bus bar Ribbon concentrates the cell stringing into junction box and channels electrical current.
About Coating Alloy:
The coating type is determined by the customer’s design and demand. It is divided into leaded and dead-free coating. At moment the leaded coating type is widely used, but in the future it will be developed to lead-free coating type.
Main coating alloy types and melting temperatures as follows:
