History of PV Ribbon Development

2BB-3BB Phase

1. Interconnect Ribbon
   • Primarily made from rolled copper strips, processed using a 48-head slow tinning machine at a speed of 10-15 meters per minute. The tinned copper strips are rolled into coils and cut into final product dimensions. Specifications range from 2.0 x 0.2 mm to 1.5 x 0.16 mm.
2. Busbar Ribbon
   • Produced by slitting copper strips and processing them with a slow tinning machine (10-15 meters per minute), then coiled and cut to the final dimensions. Specifications range from 8.0 x 0.25 mm to 4.0 x 0.15 mm.
3. Module End Welding
   • Primarily done manually, which limited production speed and consistency.

4BB-5BB Phase

1. Interconnect Ribbon
   • Transitioned from slow to fast tinning with speeds of 90-120 meters per minute. Initially, the copper strip was rolled and tinned in two separate steps, later combined into a single rolling and tinning process. Reflective interconnect ribbons were also introduced.
2. Busbar Ribbon
   • Advanced to fast tinning with speeds of 40-60 meters per minute.
3. Product Packaging
   • Finished ribbons were primarily packaged in spools.
4. Module End Welding
   • Automated welding became the primary method, increasing production efficiency.

9BB-12BB Phase

1. Interconnect Ribbon
   • Evolved into round ribbons with specifications between 0.30-0.40 mm, providing enhanced flexibility and lower resistance.
2. Busbar Ribbon
   • Transitioned to integrated rolling and tinning processes.
3. Product Packaging
   • Continued to be packaged in spools.

Current Phase

1. MBB (Multi-Busbar) Round Wire Ribbon
   • Includes standard round wire ribbons (0.29-0.32 mm) and low-temperature round wire ribbons, designed for improved compatibility with modern PV module designs.
2. Reflective Busbar Ribbons
   • Available in white or black reflective versions to enhance light absorption and module efficiency.
3. MBB Shaped Ribbons
   • Includes unique shapes like round-flat and round-triangle ribbons for specialized applications.
4. Black Ribbon
   • Black interconnect and busbar ribbons are available, which are designed for aesthetic integration in PV modules, particularly in rooftop installations.
