Description
Technical Field
The invention belongs to the field of solar cells, and particularly relates to a white packaging adhesive film for a solar cell module.
Background
At present, the problems of energy and environment are becoming more serious, and the search for a clean and sustainable new energy is urgent. The solar photovoltaic power generation industry based on the photoelectric conversion effect is gradually entering into human energy structures, wherein a solar cell module is one of products which are successfully commercialized, and is also paid attention all over the world. The solar cell module mainly comprises a high-efficiency single crystal/polycrystal solar cell piece, glass, an EVA packaging adhesive film, a back plate and an aluminum alloy frame. The EVA packaging adhesive film is a polar high-molecular compound, has strong cohesiveness, and is a conventional choice for packaging adhesive films in the existing solar cell modules.
For a solar cell module (especially a dual-glass solar cell module), because glass has high transparency, a large amount of sunlight can penetrate through the glass, and unnecessary waste is caused. Therefore, if the back surface of the cell piece is provided with the packaging adhesive film with high reflectivity, sunlight penetrating through the cell piece is reflected to the cell piece again, the loss of the sunlight is reduced, the utilization rate of the sunlight can be greatly increased, and the photoelectric conversion efficiency is further improved. Therefore, a white packaging adhesive film appears, the principle of the white packaging adhesive film is mainly to add pigments such as titanium dioxide and the like into an EVA adhesive film to improve the light reflection performance of the EVA adhesive film, and the dispersibility of titanium dioxide powder in resin directly influences the performance of each aspect of the EVA adhesive film, so that the industrial-grade titanium dioxide with nanometer size is generally adopted.
However, the existing EVA encapsulant film has the following problems: (1) because EVA is a polar high molecular compound, the EVA is not hydrolysis-resistant, is easy to decompose and yellow stain in the use process of the solar cell, and can generate PID phenomenon to cause the power attenuation of the component especially under the conditions of high temperature and high humidity; (2) the EVA packaging adhesive film has high melt index, and during the subsequent lamination process for preparing the assembly, the EVA has high melt fluidity, so that white EVA overflows to the front side of the battery piece (namely, the phenomenon of white overflow) to cause the partial shielding of the battery piece and reduce the output power and the durability of the assembly; therefore, the prior art requires that the white glue film cannot overflow to the battery piece, the bus bar and the solder strip, and cannot have the defects of wrinkles and the like.
In order to solve the problem, in the prior art, non-polar polyolefin is mostly used to replace EVA as a packaging adhesive film, for example, chinese patent application CN106684186A discloses a preparation method of a packaging adhesive film with good bonding without flanging, and the problem that the packaging adhesive film is easy to overflow is solved by preparing an adhesive film with a three-layer structure.
However, the above-mentioned packaging adhesive film has the following problems: (1) because the polyolefin molecules do not have polar groups, the material surface has poor adsorption capacity and small surface tension and is difficult to bond, inorganic pigment powder (titanium dioxide) is difficult to obtain good dispersion in polyolefin, the dispersion problem can influence the performance of each aspect of an adhesive film, and particularly after long-term use, polyolefin resin can generate the condition of adhesive failure due to insufficient cohesiveness; (2) polyolefin resins have poor resistance to wet heat aging and are prone to edge blistering and even delamination during lamination.
Therefore, the development of a white packaging adhesive film with excellent performance and capable of solving the problem of easy overflow of the packaging adhesive film is a technical problem which needs to be solved urgently in the field.

Comparison with comparative example 3 found that: the adhesive film which is not added with silane for crosslinking modification not only has low crosslinking degree, but also greatly influences the bonding property, the temperature resistance and the power generation efficiency of the product.
