1. A method for producing a solar cell string, comprising:
(S1) continuously preparing, by a film-supplying device, a film; supplying, by the film-supplying device, the film to an input end of a first horizontal section of a first continuous conveyor belt; and conveying, by the first continuous conveyor belt, the film forward every time the film is laid;
(S2) supplying, by the film-supplying device, the film to a first carrying device; transporting, by the first carrying device, the film to a side section of a second continuous conveyor belt as a first back film; transporting, by the second continuous conveyor belt, the first back film to an input end of a second horizontal section of the second continuous conveyor belt; and stacking sequentially a first solder ribbon and a first solar cell on the first back film, wherein a second half of the first solder ribbon is located on the first back film;
(S3) conveying, by the second continuous conveyor belt, a second back film forward to the input end of the second horizontal section; and stacking a second solder ribbon on the second back film and allowing a first half of the second solder ribbon to be stacked on the first solar cell;
(S4) carrying, by a second carrying device, a first front film and a pressing tool stacked together from an output end of the first horizontal section to the first solar cell; and stacking a second solar cell on a second half of the second solder ribbon; and
(S5) repeating steps (S3) and (S4) followed by heating to obtain the solar cell string, wherein after transported by the second continuous conveyor belt to an output end of the second horizontal section, the pressing tool is transferred by a transfer device to a second front film on the first horizontal section for reuse.
