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.

The photovoltaic solar cell that electric energy can be translates directly into becomes solution worldwide energy crisis and reduces the important of environmental pollution
One of method.The module that solaode is constituted generally is exposed to the sun in the sun, affects battery module in order to avoid shining upon
Temperature, and then the generating efficiency of battery module is affected, therefore special requirement solar cell backboard has good heat dispersion.
There is data to show, same photovoltaic module power station, in intensity of illumination is weak, light application time is short spring and autumn and light
According to intensity is strong, light application time length summer, its gross generation is almost without increase, or even has reduced, and therefore research worker is launched
Investigation, finally finds that the persistent fever of photovoltaic module have impact on the output of power, i other words increasing light intensity and prolongation
Light application time, in theory, with improve generating efficiency and can increase generated energy, but therefore the component fever phenomenon that brings then
Great retroaction can be played.Statistical data shows, when the operating temperature of component is more than 60 DEG C, often improves 10 DEG C, will be very big
Impact cell piece generating efficiency and electricity output.
At present, on market solar energy single crystal or polycrystalline component takes following structure, i.e., stack gradually from top to bottom and set
Put toughened glass layer, EVA layer, cell piece, EVA layer, TPT layers and aluminum alloy frame.The front glass sheet of such structure and envelope
Pay close attention to light penetration more package material, typically require more than 91%, so as far as possible can absorb photon so that cell piece more
There are higher conversion efficiency and electric power output.Notacoria mostly is fluorine-containing polymer composite, plays the protection work such as block water, insulate
With, but the problem for equally bringing radiating difficult.And heat molten type EVA adhesive film laminating packaging at high temperature is used, battery can be damaged
Piece, causes decrease of power generation.
