A solar cell back sheet and a solar cell and a method for preparing

The present invention provides a solar cell backsheet, said backsheet side of the electrostatic spray corrosion resistant layer and the other surface of the organic insulating layer comprises a metal layer, an aluminum alloy sheet, aluminum alloy sheet and the metal layer; the organic insulating layer comprising poly vinyl fluoride resin, polyvinylidene fluoride resin, polytrifluoroethylene resin, a polytetrafluoroethylene resin or a polyvinyl fluoride resin, polyvinylidene fluoride resin, polytrifluoroethylene resin, a polytetrafluoroethylene resin monomer with other resins at least one copolymer of monomers. The present invention further provides a method for preparing the back sheet and a solar cell comprising the backplane. Good adhesion between the organic insulating layer and the backsheet of the present invention, the aluminum alloy sheet layer.
