Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic materials, and in particular to a graftable condensed ring material, a color-conversion adhesive film and a photovoltaic module, and in particular to a graftable condensed ring material, a color-conversion adhesive film with high migration resistance and strong aggregation resistance made therefrom, and a photovoltaic module using the adhesive film. Background Art

[0002] Solar cell systems are one of the most promising systems due to their low environmental impact. Although solar cell systems have long been very reliable under field conditions with low degradation and failure rates, they are still susceptible to ultraviolet light in sunlight. The current effective solutions are to use cut-off films to filter ultraviolet light, but this method will lose ultraviolet energy; the second is to use films doped with color light conversion luminescent materials to achieve red shift of the wavelength of ultraviolet photons that are harmful to the cell, and transform the band to the visible light region that can be used by solar cells, thereby improving the efficiency of solar cells. However, traditional films doped with color light conversion agents have the problem of film inhomogeneity, which seriously affects the use of the film.

[0003] Therefore, in order to solve the above technical problems, it is urgent to develop a color conversion material that can be stably dispersed in the photovoltaic film. Summary of the invention

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a color conversion material that can be stably dispersed in a photovoltaic adhesive film. Specifically, the problem of uneven film in the prior art adhesive film doped with a color conversion agent is solved by grafting and cross-linking technology. The small molecule color conversion material is grafted into the adhesive film by a cross-linking method, and the small molecule and the adhesive film are directly coupled by free radical initiation and base film formation CC to form a more uniform film, thereby improving the service life of the color conversion adhesive film.

[0063] Application Example 1

[0064] A color light conversion film, the raw materials and dosage of which are shown in Table 1:

[0065] Table 1

[0066]

[0067]

[0068] The preparation method is as follows: POE particles, graftable polycyclic material Xa, crosslinking agent, modified silane, acrylate, light stabilizer and antioxidant are mixed in a formulated amount, plasticized by a screw at 105°C, and co-extruded by a die to obtain a color light conversion adhesive film, namely, a color light conversion POE film.

[0069] Application Example 2

[0070] A color light conversion adhesive film, the raw materials and dosage of which are shown in Table 2:

[0071] Table 2

[0072]

[0073] The preparation method is the same as that of Application Example 1.

[0074] Application Example 3

[0076] Table 3

[0077]

[0078] The preparation method is the same as that of Application Example 1.

[0079] Comparative Example

[0080] The preparation scheme, added medium and auxiliary agent of this comparative example are the same as those of Application Example 1, except that the graftable polycyclic material Xa is replaced with a commercial ultraviolet absorber UV326, and finally a conventional POE film is obtained after cast extrusion.

[0081] The performance comparison test of the color light conversion POE film prepared in Application Examples 1 to 3 and the conventional POE film prepared in the comparative example was conducted. The specific test detected the maximum static friction coefficient according to the GB / T 10006-2021 standard, and the comparison was repeated every month. The performance is shown in Table 4.
