1. A photovoltaic module, comprising:
a plurality of cells, each of the plurality of cells including grid structures spaced apart in a first direction;
a plurality of connection components extending along the first direction and spaced apart in a second direction; wherein each of the plurality of connection components is electrically connected to corresponding adjacent cells of the plurality of cells;
a plurality of composite films, each of the plurality of composite films covering a surface of a respective connection component of the plurality of connection components and portions of a surface of a corresponding cell on opposite sides of the respective connection component;
wherein each of the plurality of composite films includes a first layer and a second layer, and the first layer is located between the second layer and the respective connection component;
an encapsulation layer, covering surfaces of the plurality of composite films; and
a cover plate, disposed on a side of the encapsulation layer away from the plurality of cells;
wherein each of the plurality of composite films includes a first portion and a second portion, the first portion covering the surface of the respective connection component, and the second portion and surfaces of the respective connection component and the corresponding cell that correspond to the second portion enclosing a bonding gap;
each of the plurality of composite films is provided with a plurality of through holes at a position corresponding to the bonding gap, and an orthographic projection of the plurality of through holes on the surface of the corresponding cell does not overlap with an orthographic projection of the respective connection component on the surface of the corresponding cell.
