How to weld wires on solar cells?
1. Spraying the soldering flux on the main grid of the battery plate, and then welding it with the tinned copper strip. This method is used in the automatic welding machine;2, the use of flux soaked copper belt after welding, this method is mostly manual welding.
The wire on the solar cell is tin plated copper strip, and the silver paste on the battery plate is formed into a silver tin alloy layer during the high temperature welding process so as to be connected together
