How to select PV ribbon by solar cell technology?
Different cell technologies have different ribbon requirements: PERC uses standard ribbon (0.28-0.35mm), TOPCon needs ultra-thin ribbon (0.24-0.26mm), HJT requires low-temp ribbon (<180°C), BC needs reflective ribbon (0.10-0.25mm). Correct selection can improve module efficiency by 0.5-2%.

Frequently Asked Questions
How to choose the right PV ribbon thickness?
Thickness depends on cell type: PERC standard 0.2-0.35mm, TOPCon ultra-thin <0.1mm, HJT low-temp 0.15-0.25mm, BC custom 0.12-0.2mm. Thinner ribbons reduce shading but require higher soldering precision.
What is the difference between CCA and pure copper ribbon?
CCA (Copper Clad Aluminum) ribbon has an aluminum core with copper outer layer, achieving 62%+ IACS conductivity, 40% weight reduction, and 20-30% cost savings. Suitable for cost-sensitive applications with moderate conductivity requirements.
Why does HJT require low-temperature ribbon?
HJT cells use amorphous silicon passivation layers sensitive to temperature. Temperatures above 200°C can damage the amorphous silicon layer and reduce cell efficiency. Low-temperature ribbon (<180°C soldering) protects cell structure for long-term reliability.
