Efficient Solar Panel Interconnect Ribbon for Enhanced Energy Connectivity
Description
Spooling Packing Tabbing Wire/PV Ribbon for Machine Automatic Soldering Solar Cells
Solar interconnect ribbon is a kind of fine high-carbon steel wire of high strength, high hardness, and high wear resistance. It is used as the carrier for multi-wire sawing to cut super-hard crystalline materials, such as silicon, gallium arsenide, indium phosphide, silicon carbide and crystal.
