Domestic enterprises have taken the lead in developing high reflectivity, high-temperature weather resistant photovoltaic glass, with a reflectivity of up to 81%!

Solar energy is a source of energy that can meet the future needs of humanity, while photovoltaic power generation is a pure physical process that uses solar energy to convert photons into electrons. The conversion process does not emit any harmful substances, has no fuel consumption, zero emissions, no noise, no pollution, and a short investment payback period. It belongs to green new energy.

With the implementation of the 14th Five Year Plan, replacing traditional energy with new energy has become a trend, and the development prospects of the photovoltaic industry are enormous. Therefore, major enterprises have increased their investment in research and development, making every effort to improve the efficiency of photovoltaic power generation and reduce power generation costs, and being meticulous in every aspect.

Our domestic enterprises are the first to apply a highly reflective coating on the back of the ultra white glass in photovoltaic panels. This way, the solar energy transmitted from the photovoltaic panel will be reflected back into the photovoltaic panel through the highly reflective coating for secondary absorption, thereby improving the photovoltaic conversion efficiency of the photovoltaic panel.

After testing, the reflectivity of the glass coating is over 81%, which can meet the requirements of high reflectivity, high temperature resistance, scratch resistance, high hardness, high adhesion, and high weather resistance functional coatings for photovoltaic glass coatings. At the same time, this high-temperature weather resistant photovoltaic glass ink greatly enhances the secondary absorption of solar energy by photovoltaic panels, improves the photoelectric conversion efficiency of photovoltaic power generation, adds icing on the cake to photovoltaic power generation, and promotes the development of new energy. It is of great significance for maintaining our first mover advantage in the photovoltaic industry and enhancing the competitiveness of our enterprise's photovoltaic products, and has been appreciated and welcomed by major photovoltaic manufacturers.

What are the improvements in the production process of high reflection, high-temperature, and weather resistant photovoltaic glass

1、 Selected raw materials:

Choose appropriate raw materials, such as high-purity quartz sand, soda ash, limestone, etc., to ensure the quality and performance of the glass.  

2、 Glass melting:

Mix the raw materials in a new proportion and melt them at high temperature to form a uniform glass liquid.  

3、 Rolling forming:

Press the glass liquid into the desired shape and thickness, such as flat glass or curved glass, through a rolling mill.

4、 Annealing treatment:

Annealing treatment is carried out on the glass after rolling forming to eliminate internal stress and improve the strength and stability of the glass.

5、Preparation of high reflectivity coating:

Prepare a high reflectivity coating on the surface of glass to improve its reflectivity. Common coating materials include metal oxides, metal silver, etc.  

6、High temperature weather resistance treatment:

Perform high-temperature weather resistance treatment on glass to improve its high temperature resistance and weather resistance. Common processing methods include heat treatment, chemical treatment, etc.

Two major advantages of high reflectivity, high temperature, and weather resistant photovoltaic glass have been improved

1、A reflectivity of over 80% is a major breakthrough in the history of photovoltaic material research and development. High reflectivity and high weather resistance photovoltaic glass can greatly increase the utilization rate of light, reflect more light onto photovoltaic cells, improve the absorption efficiency of photovoltaic cells towards sunlight, and thus enhance the power generation of photovoltaic systems. At the same time, high reflectivity can greatly optimize the distribution of light, through reflection, making the light more evenly distributed inside the photovoltaic module, reducing local heating and energy loss caused by uneven light.

2、Highly reflective high-temperature weather resistant photovoltaic glass can maintain stable physical and chemical properties under high temperature conditions without deformation or softening.
