Description
The Low-temperature pv ribbon from Telison is specifically designed for HJT (Hetero-junction Technology) applications. Using a special low-temperature alloy immersion plating, it can achieve low-temperature soldering (below 170°) under the stable performance.HJT's low-temperature silver paste and TCO layers are sensitive to soldering temperature, so low-temperature bonding markedly reduces the impact of welding heat on the cells, which is beneficial to the thinning of cells and reducing risk of hidden cracks, suitable for low-temperature welding process. The Low-temperature pv ribbon is mainly used in HJT cells modules, and also used in Topcon and IBC cells modules.
Features
- Copper Material: Tu1, purity ≥99.97%
- Low soldering temperature: Melting point ≤170°C, protecting the HJT low-temperature process window
- Lower microcrack/chip rate: Thermal stress greatly reduced; cell microcracking and chipping are markedly lowered
- Energy saving: Lower stringer temperature setting and energy consumption; shorter cycle time
- Low-temperature silver-paste compatible: Best compatibility with HJT low-temperature silver paste and TCO layers
- Reliable under thermal cycling: Lower solder-joint stress improves module thermal-cycling reliability
- Mainly used in HJT modules,and also used in Topcon and IBC modules.
- Customization is acceptable, test report could be offered upon request

Application
The Low-temperature pv ribbon is mainly used in HJT heterojunction modules (including low-temperature SMBB/0BB interconnection) and IBC or other temperature-sensitive N-type high-efficiency cells; a critical enabler for HJT mass production, efficiency improvement and cost reduction.
Package,Transportation, Storage
Package
- In order to ensure the goods safety during transportation , Telison introduced customized wooden or carton box as outer package with label on it and packing list inside the box.
- Inner package are uniformly introduced corrugated cartons.
- Each spool is sealed with a vacuum bag and light weight material filled between them to avoid fretting and banking during transportation.
