Description
Technical Field
The invention relates to the technical field of solar cells, in particular to an enhanced photovoltaic packaging adhesive film and a preparation method thereof.
Background
The photovoltaic packaging adhesive film is an important material in the solar photovoltaic technology industry, plays an important role in bonding a battery piece with photovoltaic glass and a back plate, and simultaneously has multiple functions of mechanical buffering and protection of a photovoltaic module, PID resistance of the module and ultraviolet resistance protection of the back plate. The photovoltaic adhesive film, as a polymer material, is inevitably eroded by the natural environment to cause aging, so the photovoltaic adhesive film is one of the key materials affecting the service life and the power generation power of the photovoltaic module. The research and improvement of the photovoltaic adhesive film have important significance for the promotion of the photovoltaic industry.
The traditional photovoltaic adhesive film is made of ethylene-vinyl acetate polymer as a basic material, and is called as an EVA photovoltaic adhesive film. The chemical structure of vinyl acetate has polarity, has the defects of high water vapor transmittance, easy hydrolysis, aging and the like, and can not effectively protect the photovoltaic module in humid environments such as coast, especially the double-sided battery in the photovoltaic industry is gradually raised, and the EVA photovoltaic adhesive film can not play the role of PID resistance. The industry chain needs a new photovoltaic film meeting the requirements, and under the background, the ethylene-octene polymer photovoltaic film is claimed. Because the ethylene-octene polymer is of an all-carbon and carbon-hydrogen structure, the ethylene-octene polymer has no polarity, low water vapor transmission rate, no hydrolysis and aging, and no loss of the protection function of the photovoltaic component in a humid environment; meanwhile, under the potential condition, the molecular structure of the ethylene-octene polymer can not generate polarization and migration of charges, and the double-sided battery can still have the effect of PID resistance. The use of ethylene-octene polymer photovoltaic films has become a great trend in the photovoltaic industry.
The photovoltaic adhesive film generally comprises colloidal particles, an antioxidant, a cross-linking agent, a silane coupling agent and other auxiliaries, wherein the auxiliaries are mostly liquid, and because the ethylene-octene polymer has no polarity, the liquid auxiliaries are not completely absorbed, and are easily separated out on the surface of the adhesive film gradually along with the prolonging of the standing time, so that the adhesive film has the problems of reduced performance, poor batch stability and size uniformity, pollution during use and the like. Therefore, the problem of the precipitation of the liquid auxiliary agent of the ethylene-octene polymer adhesive film needs to be solved, and the method for adsorbing the liquid auxiliary agent by adopting the porous nano material with large specific surface area is an effective method.
The common photovoltaic module with the crystalline silicon solar cell as a power generation core is of a sandwich-like structure which is formed by laminating five parts, namely a glass front plate, a packaging adhesive film, a solar crystalline silicon cell, a packaging adhesive film and a solar cell back film, from top to bottom at high temperature; in order to ensure the strength and outdoor safety of the solar photovoltaic module, a piece of tempered glass with a relatively thick thickness of about 3.2mm is usually used as a front plate, and the tempered glass is relatively heavy, so that the weight of the solar photovoltaic module is increased greatly, and the use of the solar photovoltaic module in a roof distribution type and other civil scenes is limited.
In order to reduce the weight of the photovoltaic module, a feasible technical route is to thin the front glass plate and use a small metal frame with relatively light weight, but this brings a new problem that the snow load and wind load tests of the photovoltaic module cannot reach the design specifications. The reason for this is mainly due to the insufficient strength of the assembly resulting from the thinning of the front glass and the use of the small metal bezel.
Based on the technical scheme, the strength of the photovoltaic module is enhanced by enhancing the strength of the photovoltaic packaging adhesive film.
