The specifications for pv ribbon can vary by manufacturer and application, but here are some common pv ribbon specifications:
The width of a pv ribbon is usually measured in millimeters (mm), and common widths include 2mm, 4mm, 5mm, 6mm, and more. The width usually matches the width and alignment of the cell.
The thickness of pv ribbon is usually measured in microns (μm), and common thicknesses include 120 μm, 150 μm, 200 μm, and so on. The choice of thickness is usually related to the design of the cells and the way they are connected.
The material of pv ribbon can be copper, silver, aluminum and so on. The choice of material will affect the soldering performance and cost.
Resistivity indicates the electrical conductivity of the solder tape and is usually measured in Ω-mm²/m (ohms-millimeters²/meter). Welding tapes with low resistivity have better electrical conductivity.
Some pv ribbons have special surface coatings to improve their corrosion resistance and solderability.
The shape of pv ribbon can be flat tape, wire, tape with slits, etc. The exact shape depends on the welding requirements.
Rewind method: pv ribbon is usually supplied in rolls, which can be coiled, mandrel, spool, etc. The rewinding method affects the way the material is supplied in the welding process.
The length of pv ribbon is usually measured in kilometers (km) and can be customized to meet production and welding needs.
These specifications can be adapted to the requirements of different PV module designs and welding processes. Specific specification selection should be based on the needs of the specific application to ensure the fit and weld performance of the ribbon to the cell.
