METHOD AND DEVICE FOR SOLDERING HETERO-JUNCTION WITH INTRINSIC THIN-FILM SOLAR CELLS TOGETHER TO FORM STRING

摘要

In the present invention, disclosed is a method for serial welding of a heterojunction solar cell. The method comprises the steps of: placing a battery cell in a transfer mechanism; controlling the transfer mechanism to transfer the battery cell into a welding chamber; determining whether the temperature in the welding chamber is within a predetermined temperature range while continuing the welding on the battery cell; continuing the welding if the temperature in the welding chamber is within the predetermined temperature range; adjusting the temperature in the welding chamber to the predetermined temperature range if the temperature in the welding chamber is not within the predetermined temperature range, continuing the welding to the battery cell, and determining whether the temperature in the welding chamber is in the predetermined temperature range at the same time; and completing the welding and transferring the battery cell out of the welding chamber.
