In order to achieve the maximum light-receiving area in a limited area, the existing photovoltaic cell reduces the gap between adjacent cell sheets, that is, the edges of adjacent cell sheets are arranged in an overlapping manner. However, this will cause the solder strip to have excessive stress on the edge of the cell sheet, and the edge of the cell sheet is prone to hidden cracks or breakage. In order to solve the above problems, a film strip is currently placed between the overlapping parts of adjacent cell sheets to buffer the stress of the solder strip on the edge of the cell sheet.

[0057] The raw material of the film strip is a film roll. The film roll needs to be first cut into film sheets, and then the film sheets are cut into multiple film strips, and then the film strips are sequentially sent to a cell string group string device.
