Problems solved by technology

The frame is mainly made of aluminum profiles through cold extrusion processing. There are many processing procedures, large energy consumption, large waste, and high cost; the product is heavy, which is not conducive to the assembly and transportation of solar cells. The battery effect is formed, the components are corroded, and the service life of the product is shortened
Patent CN 113949339 A discloses a manufacturing process and material for a composite material frame. This patent uses a thermosetting composite material process. The existing problem is that the FRP product is a thermosetting plastic product. The biggest problem is that it is not environmentally friendly. It cannot be degraded by itself, and needs to be buried or incinerated on the spot, which has a bad impact on the environment. In addition, the manufacturing environment of FRP products is not friendly, and the smell and dust are large.

Abstract

The invention provides a solar cell frame material and a preparation method thereof. The preparation raw materials of the frame material comprise the following components: an annular material, reinforced fibers and an auxiliary agent in a mass ratio of (20-30): (70-80): (0.1-1), the cyclic material is selected from cyclic butylene terephthalate, caprolactam, a mixture of cyclic butylene terephthalate and caprolactone, or a mixture of caprolactam and caprolactone. Under the combined action of the components, the light weight of the material is realized, and the material also has higher mechanical strength. The material can be recycled, so that the environmental protection problem is solved, and the problems of unfriendliness, odor and large dust in the production process are reduced.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a solar cell frame material and a preparation method thereof. Background technique [0002] The energy crisis is a hot topic in this century. With the depletion of fossil energy, the energy structure will undergo major changes and adjustments, and new renewable energy will become the energy foundation of human society. It is predicted that by the end of this century, green renewable energy will account for more than 80% of the energy mix, and solar energy will account for more than 50% of renewable energy. [0003] Solar cells are mainly polycrystalline silicon, monocrystalline silicon, and polymer cells. Affected by many aspects of power generation efficiency and cost, silicon-based cells are mainly used in large-scale applications. Among them, polysilicon is widely used. According to research, polysilicon is used in solar cell panels, accounting for more than 90%...
