[0003] Compared with conventional solar cell packaging processes, the coating process uses a new type of stringer to lay low-temperature solder ribbons on the front and back of two cells to connect adjacent cells in series. The cells are then bonded and fixed with a skin film. After the connected cells are arranged and stacked, the solder ribbons are pressed together with the cell grid under certain lamination temperature and pressure to form a coated cell string.
