What are the tin bands, sinks and interconnections used on solar modules, and what are the solar cells used in the solar cells?
Light incident on the side of the general agreement for the positive, ordinary p-type battery front pn knot is the final need to use, and the back is called back knot.
At present, the general crystal silicon cells using p-type silicon, in the phosphorus diffusion process, the two sides of the silicon and the edge will be phosphorus doping.
and play the battery chip in series for the purpose of the bus bar is the current of each string The busbars and interconnections are all tinned copper strips.
The bus bar and the interconnection are of the same effect, are collected with the charge, the interconnection of a single cell is to collect the charge
