  • Publication number: 20240059933
    Abstract: The present disclosure provides an encapsulating composition, a composition, an encapsulating glue film, an electronic component and a solar cell assembly. The encapsulating composition comprises polyolefin resin, polyethylene glycol dimethacrylate and organic peroxide, and the structural formula of the polyethylene glycol dimethacrylate is represented by a formula (I). When the polyolefin resin is heated and melted, the ethylene glycol dimethacrylate is delaminated and aggregated in the polyolefin resin. A polymer network structure that has a three-dimensional network structure and that has several ester groups and ether bonds is formed in situ in a polyolefin resin matrix, and the polymer network structure may adsorb residual metal ions in the polyolefin resin, thereby reducing the mobility of the metal ions, so as to improve the dry insulation resistance of the polyolefin resin. In addition, said composition has simple components, readily available raw materials and low costs.

  • Patent number: 11905398
    Abstract: Provided are a film and an electric device comprising the same. The film comprises at least one modified polyolefin resin layer. A resin forming the modified polyolefin resin layer comprises 1-100% of modified polyolefin resin. A main chain in the modified polyolefin resin is an ethylene-?-olefin copolymer. A grafted branched chain in the modified polyolefin resin is selected from a compound formed by a vinyl monomer comprising one or more of anhydride group, hydroxyl, ester group, carbonyl, acylamino, pyridyl, epoxy, pyrrolidonyl and glycidyl. A molecular weight of the grafted branched chain is 150-8000 g/mol. The film prepared from the modified POE layer with the main chain and the grafted branched chain has excellent anti-PID performance. The layers have a better adhesive property without a laminated interface therebetween. The co-extruded film further has an excellent water vapor barrier property, a relatively high insulating property and a relatively high light transmittance.

  • Patent number: 11525043
    Abstract: The present disclosure relates to a high light transmittance photovoltaic encapsulating material, which is prepared by the following process: subjecting 100 mass parts of a photovoltaic encapsulating material matrix resin or a graft-modified matrix resin, 0.001 to 5 mass parts of an oxygen- or sulfur-containing compound, 0.01 to 10 mass parts of a reactive plasticize 0.01 to 1.5 mass parts of an initiator, 0.01 to 10 mass parts of an assistant cross-linker, 0.1 to 3.0 mass parts of a silane coupling agent, 0.1 to 0.4 mass parts of an ultraviolet light absorber, and 0.1 to 1.0 mass part of light stabilizer to pre-mixing, melt extrusion, film casting, cooling, slitting, and coiling. The light transmittance of the photovoltaic encapsulating material is improved, and the refractive indexes of glass/front-layer encapsulating material/cell match each other, thereby increasing the sunlight utilization ratio of a module, and optimizing the photoelectric conversion efficiency of the module.
