PV Ribbon
Low-Temperature PV Ribbon
Low-temperature PV ribbon uses a solder coating selected for a lower-temperature cell-interconnection process. Match the coating alloy and thickness to the cell, soldering window and stringer, then check joint strength and reliability in the module design.
Construction and specification
- Material construction
- Copper-aluminum composite or specified copper base with the coating defined by the cell process
- Product form
- Ribbon
- Surface coating
- Tin, low-temperature solder, black or reflective coating
- Thickness range
- 0.10-0.35 mm typical, custom on request
- Width range
- 0.30-2.00 mm typical, custom on request
- Supply format
- Spool, traverse wound spool or cut-to-length
Selection and processing
Low-temperature describes the selected soldering process, not a universal temperature limit. Specify the coating alloy, its required melting behavior and the actual stringer window. HJT or another cell name alone does not set ribbon dimensions or soldering conditions.
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.
Standards scope referencesProduct questions
What is low-temperature ribbon?
low-temperature ribbon is a solar module interconnection material used to collect and transfer current between solar cells or cell strings. Raytron supplies custom ribbon dimensions, coating systems and packaging formats for different PV module technologies.
How do I choose low-temperature ribbon?
Start with the cell technology and soldering temperature. Then check coating type, shading loss, yield strength, module reliability requirements and compatibility with the automated process.
Can Raytron customize low-temperature ribbon?
Yes. Width, thickness, coating, temper, spool format and packaging can be customized according to drawing, sample or module process requirements.
