1. A photovoltaic module, comprising:
a front substrate;
a first sealing member;
a back substrate;
a second sealing member, wherein a cross-linking rate of a material of the second sealing member is higher than that of a material of the first sealing member;
a solar cell string, wherein along a thickness direction of the photovoltaic module, the solar cell string is located between the first sealing member and the second sealing member, and an area of the solar cell string is smaller than an area of the first sealing member and is smaller than an area of the second sealing member; and
a pad strip, wherein the first sealing member, the solar cell string, and the second sealing member are sequentially arranged along the thickness direction of the photovoltaic module, the pad strip is located around the solar cell string, and the pad strip is located at edges of the first sealing member and the second sealing member and sandwiched between the first sealing member and the sealing member,
wherein the pad strip is made of a same material as the first sealing member, and a thickness of the first sealing member, a thickness of the second sealing member, and a thickness of the pad strip all gradually decrease along a length direction of the photovoltaic module towards an edge of the photovoltaic module,
wherein the front substrate is positioned on a front side of the solar cell string, the first sealing member is positioned between the front substrate and the solar cell string, the back substrate is positioned on a back side of the solar cell string, the second sealing member is positioned between the back substrate and the solar cell string, and the front side of the solar cell string is a receiving side.
