10. The sheet of claim 1, wherein part or all of the upper surface of the rigid support edge seal is covered by the upper layer; part or all of the lower surface of the rigid support edge banding body is covered by the lower layer.
11. The plate according to claim 1, wherein the skeleton core layer is in a honeycomb shape or a porous foaming shape or a hollowed-out frame body shape; and/or the thickness of the skeleton core layer is 5-30mm; and/or the skeleton core layer adopts a thermoplastic core layer, and the upper surface layer and the lower surface layer respectively adopt thermoplastic layers; and/or the skeleton core layer and the upper surface layer and/or the lower surface layer are compounded and formed into a whole through hot pressing and compounding or cold bonding; and/or, when the skeleton core layer is compounded with the upper surface layer and/or the lower surface layer, the rigid support edge sealing body is positioned in the interval space.
12. A photovoltaic module, characterized in that the photovoltaic module at least comprises a front packaging part, a battery string layer and a board at least comprising a framework core layer, wherein the board is a board according to one of claims 1-11, and the lower surface layer of the board is used as the back surface of the photovoltaic module.
13. The photovoltaic module of claim 12, wherein the sheet material directly acts as a carrier for the photovoltaic module when compounded.
