Embodiment 1

[0054] The packaging film manufacturing process is as follows:

[0055] First, ethylene-vinyl acetate copolymer (U.S. DuPont) 85wt%, modification aid 3-(methacryloyl chloride) propyltrimethyloxysilane (Shanghai Chunan International Trade Co., Ltd.) 10wt%, UV Auxiliary 2-(2'-hydroxyl-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole (Jinan Bangde Chemical Technology Co., Ltd.) 2wt%, anti-thermal oxygen Aging agent 2,6-di-tert-butyl-4-methylphenol (Shenghe Chemical Co., Ltd.) 1.5wt%, initiator benzoyl peroxide (Chengdu Gracia Chemical Technology Co., Ltd.) 1.5wt%, after mixing After being extruded at 60-90°C, it is cast into a film to obtain a 450-micron-thick encapsulation layer.

[0056] Then, spray-coat a reflective layer with a thickness of 160 microns on one side of the encapsulation layer on the coating line with the shape of the reflective area designed in advance. The ingredients of the reflective layer coating are 75wt% of hydroxyl acrylic resin (Mitsui Chemicals C...

Embodiment 2

[0058] First, ethylene-octene copolymer (U.S. Dow Chemical) 60wt%, modification additive 3-(2,3-glycidyloxy) propylmethyldiethoxysilane (Jinan Langhua Chemical Co., Ltd. ) 10wt% and vinyl trimethoxysilane (Jinan Langhua Chemical Co., Ltd.) 20wt%, UV additive 2,4-dihydroxybenzophenone (Shanghai Zhixin Chemical Co., Ltd.) 6wt%, anti-thermal oxygen aging agent 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (Dongguan Varisi Chemical Co., Ltd.) 3wt%, initiator 2,5-dimethyl-2,5-bis (tert-butyl peroxy)-hexane (Guangzhou Qiansheng Trading Co., Ltd.) 1wt%, mixed evenly, extruded at 80-120° C., and cast to form a film to obtain a 200-micron-thick encapsulation layer.

[0059] Then, a reflective layer with a thickness of 5 microns is coated on one side of the encapsulation layer on a coating line with a pre-designed shape of the reflective area. The reflective layer coating ingredients are polycaprolactone diol (Dacel Corporation, Japan) 60wt%, acrylic vinyl ester resin (Mitsubishi ...

Embodiment 3

[0061] First, ethylene-methyl acrylate copolymer (U.S. DuPont Chemical) 70wt%, modified auxiliary vinyltrimethoxysilane (Shanghai Chun'an International Trade Co., Ltd.) 18wt%, ultraviolet auxiliary agent 2-[4-[2 -Hydroxy-3-dodecyloxypropyl]oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine ( Jinan Bond Chemical Technology Co., Ltd.) 8wt%, anti-thermal oxygen aging agent 2-[4-[2-hydroxy-3-dodecyloxypropyl]oxyl]-2-hydroxyphenyl]-4,6 - Bis(2,4-dimethylphenyl)-1,3,5-triazine (Sanhe Chemical Co., Ltd.) 2.5wt%, initiator o,o-tert-amyl-o-(2-ethyl Hexyl)-mono-peroxycarbonate (Chengdu Gracia Chemical Technology Co., Ltd.) 1.5wt%, mixed evenly, extruded at 80-120°C, and cast to form a film to obtain a 200 micron thick encapsulation layer.

[0062] Then, a reflective layer with a thickness of 180 microns is coated on one side of the encapsulation layer on a coating line with a pre-designed shape of the reflective area. The ingredients of the reflective layer coating are 8...

Abstract

The invention relates to a high reflection gain type photovoltaic packaging glue film and applications; the packaging glue film comprises a package layer and a reflection layer; the package layer is 200-500 micron in thickness, and comprises a first body resin, a modified auxiliary agent, a UV auxiliary agent, an anti-heat and oxygen aging agent and an initiator, wherein said materials are mixed and fused at 60-200 DEG C, thus forming the film through the film casting technology; the reflection layer is 5-200 micron in thickness, and comprises a second body resin, an auxiliary resin, a first filling, a second filling, a modified auxiliary agent, a diluents, a UV auxiliary agent, an anti-heat and oxygen aging agent and an initiator, wherein said materials are mixed and coated on the surface of the package layer, and solidified at the temperature of 30-150 DEG C so as to form the reflection layer. The preparation technology is simple and low in cost, and the product is excellent in performance, thus providing effective gain effect for a double-face crystal silicon cell assembly, providing basis for cost optimization of one side crystal silicon cell assembly gain type packaging material, and simultaneously providing stability and reliability of the crystal silicon photovoltaic assembly in outdoor long time applications.

Description

technical field [0001] The invention belongs to the field of photovoltaic encapsulation materials, in particular to a high reflection gain type photovoltaic encapsulation adhesive film. Background technique [0002] Photovoltaic power generation is the process of directly converting solar radiation energy into electrical energy by using the photoelectric effect. The basic device for photoelectric conversion is solar cells, which have three advantages of permanence, cleanliness and flexibility. Due to the long service life of solar cells, as long as the sun exists, solar cells can be used for a long time with one investment; compared with thermal power generation and nuclear power generation, solar cells are favored by various countries due to their simple production process, high safety in the preparation process, and strong reproducibility. It is favored by enterprises and organizations and has broad development prospects. [0003] Photovoltaic power generation system is ...
