Back-side connection of solar cells
Back-side welding is to connect 36 cells in series to form a component string. The process we currently use is manual. The positioning of the battery mainly relies on a film mold plate with 36 grooves for placing the battery cells. The size of the groove corresponds to the size of the battery. The position of the groove has been designed. Different specifications of components use different templates. The operator uses a soldering iron and solder wire to weld the front electrode (negative electrode) of the "front battery" to the back electrode (positive electrode) of the "back battery". In this way, the 36 cells are connected in series in turn and leads are welded to the positive and negative poles of the component string.
