Welding method for flexible and rollable silicon-based solar module

A welding method for a flexible and rollable silicon-based solar module, comprising the following steps:

• cutting a cell piece into a small piece cell string comprising N small piece cells without splitting by laser cutting;
• cutting a hard protective layer into N small pieces according to a size of each of the N small piece cells;
• allowing a cut hard protective layer to be covered on and bonded to a glue-dispensed small piece cell string by an automatic arrangement equipment to form a small string cell piece;
• arranging the small string cell piece into a small standard piece according to a required size distribution, and covering the small standard piece with an adhesive film;
• welding positive electrodes of the small standard piece covered with the adhesive film in series simultaneously and welding negative electrodes of the small standard piece covered with the adhesive film in series simultaneously by an automatic welding equipment to form a 1P standard part;
• and
• arranging the 1P standard part by the automatic arrangement equipment, and fixing the 1P standard part by bonding the adhesive film to each other to form a 5P standard part.
