Copper-Aluminum Composite PV Ribbon & Busbar Ribbon
Copper-Aluminum Composite Interconnect Ribbon
Composite interconnect ribbon joins solar cells into strings using a copper-aluminum conductor with a solderable surface. Ribbon geometry, coating and mechanical properties need to work with the cell layout and stringer. Send the cell drawing, process window and spool requirements to discuss samples.
Construction and specification
- Material construction
- Copper-aluminum composite or specified copper base with the coating defined by the cell process
- Product form
- Interconnect ribbon
- Width range
- Common PV ribbon widths; custom dimensions by drawing
- Thickness range
- PV module interconnection thickness range; custom by module design
- Surface
- Tin or solder coating options by soldering process
- Packaging
- Spool, traverse wound spool or customer-specified package
Selection and processing
Interconnect ribbon joins cells. Pad layout, stringing conditions, mechanical condition, camber and spool handling determine the trial specification. Record joint strength and resistance before module-level reliability checks.
Standards context
Use the drawing and a material/form-specific purchase specification. Round-wire references do not qualify rolled strip, foil or flat wire. Confirm edition, methods and acceptance criteria.
