Anti-glare and weather-resistant composite material

Abstract

The invention discloses an anti-dazzle weather-proof composite material which is characterized by comprising a surface protecting layer, a light antireflection layer, a high transmitting plastic base layer doped with quantum dots and a high transmitting packaging material layer which are stacked sequentially from top to bottom. The surface protecting layer is made of polyvinylidene fluoride materials, the light decreasing layer comprises N plastic mixed layers with fluorine plastic mixed with acrylate plastic, and the N is larger than or equal to 1 and smaller than or equal to 9. Weight proportioning of the fluorine plastic in the N plastic mixed layers decreases gradually, and the refraction index increases gradually. The packaging composite material can serve as a solar cell front plate material, the refraction index of the N plastic mixed layers can be increased sequentially due to the fact that the proportioning of the fluorine plastic in the N plastic mixed layers decreases, therefore, transmittance is increased further, and the reflection index is lowered. Meanwhile, front plate mirror reflection can be reduced, light pollution is reduced, and dazzle is prevented. In addition, heat generation resources can be decreased due to addition of the quantum dots in the plastic base layer, and the photoelectric conversion efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of photovoltaics, and in particular relates to an anti-glare and weather-resistant composite material that can be used for solar cell components. Background technique [0002] With the development of human civilization, the world is facing serious energy crisis and environmental pollution. Among them, photovoltaic solar cells, which directly convert solar energy into electrical energy, have become one of the important methods to solve the world's energy crisis and reduce environmental pollution. Modules made of solar cells are usually exposed to the sun. In order to avoid solar radiation from affecting the temperature of the battery module, thereby affecting the power generation efficiency of the battery module, it is particularly required that the solar battery backplane has good heat dissipation performance. [0003] Research data show that the same photovoltaic module power station, in spring and autumn w...

Problems solved by technology

The back film is mostly made of fluorine-containing polymer composite materials, which play protective functions such as water blocking and insulation, but it also brings about the problem of difficult heat dissipation

Moreover, the use of hot-melt EVA film to laminate and package at high temperature will damage the cells and reduce the power generation efficiency.
