Photovoltaic module

The photovoltaic module comprises a battery string, a first film layer, a second film layer, a first protective layer and a second protective layer, the first film layer and the second film layer are attached to the two opposite sides of the battery string, the first protective layer is attached to the side, away from the battery string, of the first film layer, and the second protective layer is attached to the side, away from the battery string, of the second film layer. The first protection layer and/or the second protection layer are/is of a composite structure formed by alternately arranging hard light-transmitting materials and soft light-transmitting materials. Therefore, when the composite structure is impacted by hail, kinetic energy generated by impact can be further consumed in transmission of different media, and small impact can be caused to the battery string. And when one of the first protection layer and the second protection layer is of a composite structure and the other one is made of a har
