| titleOfInvention | Solar cell back panel film and preparation method thereof |
| abstract | The invention relates to a solar cell back panel film and a preparation method thereof. The solar cell back panel film comprises a first transition layer, a first weather-resistant layer, a second transition layer, a substrate, a third transition layer and a second weather-resistant layer from top to bottom, wherein the substrate and the second and third transition layers are bonded by an adhesive layer; the first transition layer, the first weather-resistant layer and the second transition layer are three composite film layers prepared by way of coextrusion casting or film blowing; and the third transition layer and the second weather-resistant layer are two-layer composite films prepared by way of coextrusion casting or film blowing. The solar cell back panel film has the following beneficial effects that the solar cell back panel film has excellent weather resistance; introduction of the transition layers effectively improves the adhesiveness between the back panel film and the EVA adhesive layer as well as between the weather-resistant layers and the substrate; and meanwhile, the back panel film has tight structure, less production processes and low cost and does not cause solvent pollution. |
