1. A manufacturing method of a photovoltaic solar cell module, comprising the steps of:
S1: arranging a plurality of leading connecting ribbons in an orderly manner, placing a first cell on the leading connecting ribbons, arranging a plurality of metal connecting ribbons in an orderly manner and placing the metal connecting ribbons on the first cell, and placing a main jig on a middle part of an upper side of the first cell to compress the metal connecting ribbons and the cell, wherein a length of the metal connecting ribbon is greater than a length of the cell;
S2: placing a second cell on the metal connecting ribbons beyond the cell, and then arranging a plurality of metal connecting ribbons in an orderly manner and placing the metal connecting ribbons on the second cell, placing an auxiliary jig on one side of the main jig, laminating the metal connecting ribbons on surfaces of the two adjacent cells by the auxiliary jig, and placing the main jig on a middle part of an upper side of the second cell;
S3: repeating the step of S2 according to needs to form an element cluster, that is, a cell string with the main jig and the auxiliary jig;
S4: heating the element cluster to complete welding of the metal connecting ribbons and the cells; and
S5: taking down all the main jig and the auxiliary jig, applying an adhesive pattern at a designated position on a first surface of the cell string and performing curing, inverting the cell string, and applying an adhesive pattern at a designated position on a second surface of the cell string and performing curing, in order to complete fabrication of the cell string.
