Abstract: Provided is a method for fabricating a photovoltaic module. The method includes: providing a cell sheet having a predetermined thickness, and cutting the cell sheet along a direction parallel to busbars of the cell sheet, to form cutting lines on a surface of the cell sheet; splitting the cell sheet along the cutting lines, to obtain multiple cell pieces; coating, for each of the cell pieces, a conductive adhesive material on a busbar located at an edge of the cell piece; arranging the multiple cell pieces in a preset overlapping manner; curing the conductive adhesive material among the cell pieces, to form a cell string in which the cell pieces are conductively connected; and encapsulating the cell string to obtain the photovoltaic module.
