Beschreibung
Zusammenfassung:	The utility model provides an improved back board structure of a solar module, which comprises a PET (polyethylene terephthalate) substrate, a PE film (polyethyene film) and at least one first coating layer, wherein the PE film is attached to the surface of the PET substrate, and the first coating layer is arranged on the other surface of the PET substrate, and the first coating layer contain teflon (polytetrafluoroethylene, PTFE) coating. Therefore, the improved back board structure of the solar module is capable of enabling the PET substrate and the first coating layer to be matched with each other and maintain good weather resistance, electrical insulation and mechanical strength. In addition, the improved back board structure of the solar module is stably combined with a solar cell by utilizing the arrangement of the PE film, thereby achieving the effects of improving the weather resistance, sunlight utilization efficiency and structural stability.
