Tinned copper flat wire are widely used in the solar power industry as interconnect ribbons which are soldered onto the silicon cell – take away the energy produced photoelectrically. The connection of these interconnect ribbons with the rectifier takes place via the so-called busbars – slightly larger copper ribbons that are also tinned. Raytron provides our customers who produce PV interconnect ribbons and busbars with copper flat wire rolled from round copper wire.
