1. A photovoltaic curtain wall, comprising:
a first cover plate, a cell string, and a second cover plate stacked sequentially in a first direction; and
an encapsulation film disposed between the first cover plate and the second cover plate and wrapping the cell string, wherein the encapsulation film includes a first adhesive film and a second adhesive film, the first adhesive film is attached to the first cover plate, and the second adhesive film is attached to the second cover plate;
wherein the second cover plate has a thickness greater than or equal to an equivalent thickness, and the first cover plate has a thickness less than the thickness of the second cover plate;
wherein the equivalent thickness is a thickness of a target cover plate that is made of a same material as the second cover plate and that undergoes a preset bending deformation in response to a preset load;
wherein the thickness of the second cover plate is less than or equal to 6 mm, or in a range of 8 mm to 12 mm, or greater than or equal to 15 mm, and wherein:
in the case the thickness of the second cover plate is less than or equal to 6 mm, the second adhesive film has a thickness in the range of 0.7 mm to 1.6 mm;
in the case the thickness of the second cover plate is in the range of 8 mm to 12 mm, a thickness of the second adhesive film is in a range of 1.1 mm to 1.6 mm; and
in the case the thickness of the second cover plate is greater than or equal to 15 mm, the second adhesive film has a thickness in a range of 1.5 mm to 3 mm; and
wherein the first adhesive film has a thickness in a range of 0.35 mm to 0.88 mm.
