Abstract

The invention provides a solar cell backboard film. The solar cell backboard film comprises a bottom layer, a reinforcing layer and a surface layer from the bottom up in sequence; the surface layer is prepared from the following raw materials in parts by mass: 20-40 parts of low-density high pressure polyethylene, 20-40 parts of polyurethane and 10-15 parts of polybutylene terephthalate; the reinforcing layer is prepared from the following raw materials in parts by mass: 20-40 parts of low-density high pressure polyethylene, 30-40 parts of carbon nanotubes, 20-40 parts of polyurethane and 10-15 parts of polybutylene terephthalate; and the surface layer is prepared from the following raw materials in parts by mass: 30-40 parts of carbon nanotubes, 20-40 parts of polyurethane and 10-15 parts of polybutylene terephthalate. By adding carbon nanotubes to the solar cell backboard film material, the weather resistance of the material can be improved effectively, the corrosion resistance, the aging resistance, high and low temperature resistance, oxidization resistance and the like of the solar cell backboard film material are improved, and the service life of the solar cell backboard film is prolonged.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a solar battery back plate film. Background technique [0002] A solar cell is a device that uses the principle of photoelectric conversion to convert the sun's radiation into electrical energy through a semiconductor. This photoelectric conversion process is usually called the "photovoltaic" effect, so solar cells are also called photovoltaic cells. The solar cell backsheet film is located on the outermost layer on the back of the module, and is used to protect the solar cell module from water vapor erosion and block oxygen to prevent oxidation in an outdoor environment, so as to improve the service life of the solar cell module. Based on the above use conditions and functions of the solar cell backsheet film, it is usually required that the solar cell backsheet film itself has good comprehensive properties, such as high and low temperature resistance, agin...
