With the advance of technology, dual glass assembly gradually gets into people's field of vision. Double glass assembly adopts high reflection to plate glaze backplate glass and replaces traditional backplate, and high reflection plates glaze backplate glass and utilizes the space between battery piece and the battery piece to plate the glaze and scribble whitely, will see through the sunlight reflection in solar wafer clearance to the surface of solar wafer, makes sunlight can reutilization, promotes the absorptive capacity that double glass photovoltaic module set a light, reaches the effect that hinders light reflection promotion subassembly power. By combining the technology of the PERC, HJT, PERT, topcon and other double-sided batteries, the glazed double-glass component can realize double-sided power generation, but the cost is not obviously increased, and meanwhile, the power generation gain of 10-30% is realized at the system end. Therefore, each component manufacturer has introduced the grid-type high-reflection glazed glass on a large scale.
Due to the fact that the development time of the photovoltaic back plate glazing technology is short, the performance standard of the glazing back plate glass for the photovoltaic module does not form a national standard, and the performance requirements of the current market on the glazing glass mainly comprise reflectivity, adhesive force, weather resistance, EVA (ethylene vinyl acetate) bonding strength and Potential Induced Degradation (PID) resistance. The white high-reflection glaze for the photovoltaic back plate is few in research manufacturers in China, the reflectivity of most of the photovoltaic high-reflection glaze applied at present can be more than 75%, the adhesive force is 0-1 level, and the basic requirements of customers are met.
However, with the wide application of the glazed back plate glass, recently, component factories always have problems in the application process of the feedback glazed back plate glass, such as low mechanical load of the glazed back plate glass, poor foreign body impact resistance, and even easy spontaneous explosion.
Therefore, the impact resistance and reflectivity of the photovoltaic back plate glass are improved, and the photovoltaic back plate glass has important significance.
Disclosure of Invention
The current glazed back plate glass has low mechanical load, poor foreign body smashing and falling resistance and even easy self-explosion. The high-reflection glaze material with the white grids is silk-printed on the photovoltaic back plate glass, the heat absorbed by the area plated with the high-reflection glaze material with the white grids is different from the heat absorbed by the area not plated with the high-reflection glaze material when the photovoltaic back plate glass is tempered, and meanwhile, the expansion coefficient of the glass flux used by most of the conventional high-reflection glaze material is not matched with the expansion coefficient of the substrate glass, so that the strength of the high-reflection glaze layer is lower than that of the glaze-free area, and the stress of the whole glass is uneven and lower, and the flatness and the curvature of the glass are larger, so that the glazed glass has low mechanical load resistance and is easy to explode in the using process.
The present invention is directed to solving at least one of the problems of the prior art described above. Therefore, the glaze material provided by the invention can be used for preparing a glaze layer with excellent impact resistance and improving the impact resistance of the photovoltaic back plate glass.

The test results are shown in table 1.
TABLE 1
As can be seen from table 1, the glaze strips of examples 1 to 3 were broken at 800mm or 900mm, while the glaze strips of comparative examples 1 and 2 were broken at 300mm or 400mm, when the impact strength test was performed, i.e., the impact strength of the photovoltaic back sheet glass of examples 1 to 3 was significantly greater than that of the photovoltaic back sheet glass of comparative examples 1 and 2, showing that the photovoltaic back sheet glass prepared according to the present invention has excellent impact resistance.
