1. A functional part, configured to form a photovoltaic module with a cell string including a plurality of cells, adjacent cells of the plurality of cells sharing an overlapped region, the functional part comprising:
a first adhesive film and a second adhesive film, each of the first and second adhesive films comprising:
a first surface to face the cell string;
a second surface opposite to the first surface; and
at least one groove extending depth-wise from the first surface toward the second surface, a position of each of the at least one groove corresponding to a position of at least one overlapped region;
wherein the first surface includes a central region and a peripheral region at an outer side of the central region;
wherein a portion of the at least one groove is in the peripheral region, another portion of the at least one groove is in the central region, and the portion of the at least one groove in the peripheral region is separated from another portion of the at least one groove in the central region;
wherein each groove facing a respective overlapped region in the peripheral region has a first capacity, each groove facing a respective overlapped region in the central region has a second capacity, and the first capacity is larger than the second capacity; and
wherein the at least one groove in the first adhesive film and the at least one groove in the second adhesive film are staggered in terms of position, and each of the at least one groove in the first adhesive film and the at least one groove in the second adhesive film crosses a plurality of overlapped regions.
