Abstract
The invention discloses an insulating back plate for a novel solar photovoltaic battery and a preparation method thereof. The insulating back plate comprises a structure enhancement layer, an adhesive layer, a weather-resistant layer and an E binding layer, wherein the weather-resistant layer is in heating compound with the surface of the adhesive layer not facing one side of the structure enhancement layer, and the E adhesive layer is directly combined on the surface of the other side of the structure enhancement layer. The insulating back plate for the novel solar photovoltaic battery has the advantages that the E adhesive layer is in heating compound with the structure enhancement layer without adhesive directly, the combination is good, the E adhesive layer can be directly compounded with the structure enhancement layer during the production of films, and the cost is effectively lowered, and the productivity is improved.
