Description
BC (Back-Contact) ribbon features a front-side grid-free, back-contact design for higher module efficiency and reliability. It precisely matches high-accuracy rear-side electrodes, solves stress issues from traditional single-sided soldering and enhancing module reliability. It achieves maximized light absorption and efficient current collection through high-precision back-side interconnection and a front-side grid-free design.
Features
- Grid-Free Front Side: The cell's light-receiving surface has no metal shading, fundamentally eliminating the optical shading loss of conventional ribbons..
- Precision Alignment: Matches high-accuracy rear-side electrodes.
- Enhanced Reliability: Solves stress issues from traditional single-sided soldering.
- Diverse Forms: Can be flat, round, or profiled (e.g., triangular) to adapt to different back-side designs and current collection needs.
- Advanced Connection Technologies: Often involves special processes like low-temperature soldering, conductive adhesive bonding, or film lamination to protect the complex back-side cell structure.
- Customization is acceptable
- Test Report could be offered upon request
Specifications
- Copper Material: Tu1, purity ≥99.97%
- Solder Coating: According to customer's requirement
- Scope of Width: 0.50mm-2.00mm
- Scope of Thickness: 0.10mm-0.25mm
Application
The ribbon for BC cell from telison is mainly used in the latest Back-contact (BC) Cell Technology, to electrically connect individual solar cells in series, transmitting the generated current.
