Photovoltaic module

A photovoltaic module, comprising:

• a first cover plate, a first adhesive film, a plurality of cells, a second adhesive film, and a second cover plate;
• wherein a thickness of each respective cell of the plurality of cells is in a range of 100 μm to 170 μm, a thickness of the first adhesive film is in a range of 300 μm to 550 μm, a thickness of the second adhesive film is in a range of 300 μm to 710 μm, and the thickness of the first adhesive film and the thickness of the second adhesive film satisfy the following relationship:
• 0.0007x2−0.4297x+374.2≤y≤0.0034x2−1.0297x+314.19, wherein x denotes the thickness of the first adhesive film, and y denotes the thickness of the second adhesive film;
• the photovoltaic module further comprising at least one welding strip, wherein one end of each respective welding strip is disposed on a front surface of one of two respective adjacent cells in the plurality of cells, and another end of the respective welding strip is disposed on a rear surface of the other of the two respective adjacent cells, wherein a thickness of the each respective welding strip is in a range of 200 μm to 400 μm.
