Cell Breakage
Solution Soft-tempered ribbons with controlled yield strength minimize mechanical stress.
Frequently Asked Questions
What types of PV ribbons do you offer?
We offer a wide range including standard flat interconnect ribbons, bus bars, and specialized LCR (Light Capturing Ribbon) grooved ribbons designed to reflect more light onto the cell surface.
How do your ribbons ensure long-term reliability?
Our ribbons are manufactured with high-purity copper and precise solder coatings. They are engineered with optimized Yield Strength and Elongation properties to withstand thermal expansion and contraction cycles, tested to IEC 61215 requirements.
Are they compatible with new cell technologies?
Yes, we have solutions compatible with PERC, TOPCon, and HJT cell technologies, including ultra-soft ribbons for thinner wafers to minimize breakage.
Not Recommended / Validation Boundaries
- Do not substitute ribbon only from width and thickness.
- Module power impact and reliability data should be reviewed before mass adoption.
- Material substitution without application validation and customer approval is not recommended.
- Specifications and acceptance criteria must be confirmed per product form and purchase order.
