Description

technical field [0001] The invention relates to a composite material, in particular to a high light-transmitting composite material and a preparation method thereof. Background technique [0002] Affected by the dual pressures of world energy shortage and environmental pollution, the development and utilization of solar energy has become an important part of the sustainable development strategies of various countries, and the solar photovoltaic industry has received more and more attention. However, among the various factors that determine the conversion efficiency of crystalline silicon solar photovoltaic cells and light energy conversion efficiency, the most important determinant is the crystalline silicon technology in the photovoltaic cell module, followed by the photovoltaic glass that protects the photovoltaic cell module. Since crystalline silicon cannot be exposed to the external environment for a long time, photovoltaic glass is currently one of the best materials t...

However, photovoltaic glass is the auxiliary material that accounts for the largest cost in photovoltaic cells. At present, there are two main types of solar photovoltaic glass. One is ultra-clear patterned glass, which is mostly produced by calendering. The production of the original sheet mainly includes ingredients, dissolution, and calendering. The four production processes of cutting and cutting, and the original sheet is further processed by edging and tempering to obtain solar photovoltaic embossed tempered glass. The production process of this kind of solar photovoltaic glass is complicated and costly, so the cost performance is low

The other is ultra-clear float glass, which includes an ultra-clear float glass substrate, and two layers of light anti-reflection coatings are coated on the upper surface of the substrate from the inside to the outside, wherein the outer layer of light anti-reflection coating is nano-dioxide Silicon, the inner light anti-reflection coating is nano-zirconia, but this kind of solar photovoltaic glass has low light transmittance and poor weather resistance, and the uniformity of the film cannot be guaranteed by the roll-off coating method, resulting in the light transmittance of the film.
