Problems solved by technology

Because the rigidity of the back film of the battery is not enough, and the weight of the glass is too heavy, it is not conducive to the packaging and arrangement of solar cell modules
To make a support for solar cell modules, it is required to have good hardness, otherwise it is easy to cause problems such as wrinkles during the production process of solar cell modules, resulting in defects or failures of the modules

Abstract

The invention discloses a solar cell module support member which comprises a surface layer of a support member, and a bottom layer of the support member, wherein a surface layer formed by a norbornene copolymer, PA (polyamide) or PP (Propene Polymer) or PVDF (Polyvinylidene Fluoride), MAH-g-POE and eutectic of a filler is used as the surface course of the support member, the bottom layer is formed by a POE layer arranged on the lower surface of a base layer, and the POE layer can be one or two. The solar cell module support member provided by the invention has better mechanical property, has the characteristics of humidity and heat ageing resistance, tearing and hydrolysis resistance, high water vapor barrier property, high insulation property, high strength, size stability and fatigue resistance, and is beneficial to protection of a solar cell module and prolonging of the service life of the solar cell module.

Description

technical field [0001] The invention relates to the field of solar cell components, in particular to a support for the solar cell component. At the same time, it also relates to a processing technology for a support member for solar battery modules. Background technique [0002] With the improvement of solar cell module packaging technology, there are more and more packaging materials for solar cell modules, such as back film, glass and other packaging materials, which are used to support and fix solar cells and protect solar cell modules. Because the rigidity of the back film of the battery is not enough, and the weight of the glass is too heavy, it is not conducive to the packaging and arrangement of the solar cell module. To make a support for solar cell modules, it is required to have good hardness, otherwise it is easy to cause problems such as wrinkles during the production process of solar cell modules, resulting in defects or failures of the modules. At the same ti...
