Embodiment Construction

[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0017] A corrosion-resistant solar backsheet structure includes a PET base material 3, a high-temperature corrosion-resistant coating 5 is bonded to one side of the PET base material 3 through an adhesive layer 2, and a weather-resistant layer 1 is bonded to the surface of the weather-resistant layer 1. The PET base material The other side of the material 3 is bonded to the weather-resistant adhesive layer 4 through the adhesive layer 2. The high-temperature corrosion-resistant coating is made of epoxy resin composite material, and the thickness of the high-temperature corrosion-resistant coating 5 is 0.1-1 μm. The thickness of the PET substrate 3 is 80-400 microns, the thickness of the adhesive layer 2 is 0.5-40 microns, and the thickness of the weather-resistant adhesive layer 4 is 40-60 microns.

[0018] The material of the weather-resi...

Abstract

The invention relates to a corrosion resistant solar backplane structure, including a PET substrate and a high temperature corrosion resisting coating layer on one side of the PET substrate coated by an adhesive layer. The surface of the weather resisting layer is adhered by a weather resisting layer. The other side of the PET substrate is bonded with the weather resisting layer through the adhesive layer. The materials adopted by the weathering layer of the solar cell backplane are a weathering layer with fluorine. The structure of the invention has advantages of being manufactured at a low cost, providing good environmental performance and mechanical properties as well as good bonding strength. Compared with a traditional backplane, the backplane structure of the invention is more stable and more prominent to achieve a supporting protective effect. Further, the structure provides a solar battery backplane that is obviously better than an existing backplane. The arrangement of a polyester film enhances electrical insulation, moisture separation, and resistance against damp, heat and aging. With a long service life, high reflectivity and excellent anti-aging properties, the high temperature corrosion resisting coating is arranged not only to improve the corrosion resistance of a solar backplane for longer service life, but also to make the solar backplane suitable for high temperature environments.

Description

technical field [0001] The invention relates to the field of solar back panels, in particular to a corrosion-resistant solar back panel structure. Background technique [0002] Solar energy, as a green and inexhaustible energy source, is undoubtedly the best choice to replace traditional thermal power generation. Since solar cells need to be exposed to the outdoors for a long time, the cells in photovoltaic modules need to be protected to prevent atmospheric pollution. The impact and overlooking of environmental factors such as water vapor, oxygen, and ultraviolet rays. The solar backsheet is one of the accessories of the whole solar cell. It mainly plays the role of mechanical support and protection of the cells from the penetration of environmental factors. At present, the performance of the solar backsheet of the existing structure is unstable, and it is easily corroded by the influence of bad weather for a long time. , which greatly affects the service life of the solar...
