NOVELTY - Preparing graphene solar cell back sheet involves preparing the raw material of graphene-polyethylene composite master batch in proportion, where raw materials include polyethylene powder, graphene material, and additives. The graphene-polyethylene composite master batch is prepared. The polyethylene resin master batch, the graphene-polyethylene composite master batch and the polyester resin master batch are heated and melted. The obtained melt is subjected to three-layer co-extrusion, processed into a three-layer co-extruded film, and finally cut to obtain a graphene solar cell back sheet. USE - Method for preparing graphene solar cell back sheet ADVANTAGE - The graphene has excellent anti-ultraviolet, anti-aging performance, which can prolong the service life of the solar battery, at the same time, the solar conversion efficiency is improved. The graphene coat the linear polyethylene, reduce the graphene sheet stacking, graphene a layer of shielding effect, so the obtained back plate has excellent ultraviolet resistance, anti aging performance.
