1. A method for manufacturing a photovoltaic module, comprising:
providing at least one cell string, wherein a respective cell string of the at least one cell string includes N cells arranged in sequence along a same direction, and an end portion of each cell of the N cells is stacked with an end portion of an adjacent cell, such that every two adjacent cells form a corresponding overlapping welding region, N being greater than 1;
for each overlapping welding region, forming a film insertion opening between stacked end portions of the two adjacent cells corresponding to the respective overlapping welding region;
providing at least one film strip, and inserting a part of each film strip into a corresponding film insertion opening, with a remaining part of each respective film strip exposed outside the corresponding film insertion opening;
moving the at least one cell string relative to the at least one film strip, such that the remaining part of each respective film strip is at least partially inserted into the corresponding film insertion opening; and
closing each film insertion opening so that a respective one of the at least one film strip is inserted between every two adjacent cells forming a respective overlapping welding region corresponding to a respective film insertion opening.
