Description

Background
Photovoltaic cover plate glass is a coated glass who is applied to the photovoltaic module surface, and its main function is when guaranteeing light transmission, and protection crystal silicon battery avoids receiving external environment's destruction. The photovoltaic cover plate glass is produced by coating one or more layers of antireflection films formed by metal, alloy or metal compound on the surface of the glass. The anti-reflection film with reliable performance can effectively improve the efficiency of the solar cell. However, in the outdoor installation and use process of the photovoltaic module, dust or industrial pollutants can gradually cover the coated cover plate glass, so that the light transmittance of the glass is reduced, the film layer structure is damaged, the anti-reflection failure phenomenon occurs, and the efficiency of the solar cell is finally reduced by 20-40%.
At present, pollutants on the surface of photovoltaic cover plate glass are mainly cleaned in a high frequency mode manually or mechanically, but the service life of an anti-reflection film of the cover plate glass can be influenced by the high frequency cleaning, and particularly in a severe damp and hot environment, the service life of the anti-reflection film can be greatly shortened. In order to solve the problem, industrial researchers mainly focus on research on enhancing the durability of the photovoltaic module cover plate glass antireflection film, but do little research on the repair and synergy of the photovoltaic module antireflection film with long installation time in the past year, because the process of removing the low-efficiency antireflection film is complex and high in cost, and the environmental pollution risk caused by fluoride exists. However, the installed capacity of the photovoltaic module is continuously increased, and the photovoltaic module installed in an early stage gradually enters an aging period. For the reasons, the repair synergy problem of the glass antireflection film is more and more important.
In contrast, a method for cleaning and etching the ineffective antireflection film of the coated glass of the photovoltaic module, removing the ineffective antireflection film, then performing surface treatment and preparing a new nano antireflection film on the ineffective antireflection film is researched to construct a new synergistic double-layer broad-spectrum antireflection film antireflection system, but the process for removing the antireflection film by the method is complex, and the repair effect is still to be improved. Therefore, the water-based repair coating liquid for the cover plate glass of the photovoltaic module, which can effectively repair the antireflection film and improve the use efficiency of the antireflection film without removing the failure film layer, is needed to be provided.

The light transmittance test is carried out under the same conditions, and the result shows that compared with the example 2, the repair coating liquid of the comparative example 3 is adopted for repair under the same conditions, the light transmittance is improved by only 1.8% within the range of 380-1100 nm, and the light transmittance is reduced by more than 25% compared with the example 2. Meanwhile, the results of weather resistance detection experiments show that the absolute values of the delta T of salt spray test, constant temperature and humidity, outdoor exposure, ultraviolet test, friction test, acid resistance test, humidity freezing test and PCT are all obviously greater than that of the delta T in example 2. Therefore, the concentration of the film forming substance can be effectively improved by increasing the content of the components, the reaction can be carried out more completely, and the light transmittance and the durability of the film layer can meet the requirements after the film is repaired and formed.
The present application has been described in detail with reference to the embodiments, but the present application is not limited to the embodiments described above, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present application. Furthermore, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
