Description
Technical Field
The invention relates to a solar cell packaging adhesive film, in particular to a water vapor barrier type anti-aging white EVA packaging adhesive film and a preparation process thereof, and particularly relates to a white EVA packaging adhesive film for packaging a single glass assembly, belonging to the field of photovoltaics.
Background
At present, the packaging modes of the photovoltaic module are various, but no packaging mode is required for module terminal manufacturers, so that the performance of the packaging adhesive film is excellent enough, the module can be protected to stably operate for a long time, and meanwhile, the power can be expected to be improved as much as possible in a limited module space. The white EVA packaging adhesive film is taken as a gain product, and the unique high reflection advantage of the white EVA packaging adhesive film can improve light utilization, so that component power improvement is brought, and the white EVA packaging adhesive film is favored by component terminal manufacturers. And because the process is mature compared with the POE production process, the additive has good compatibility, good processing performance and good matching property with the irradiation process, and no small amount of demand exists in the packaging adhesive film market all the time.
Although a large number of module end-users are interested in white films, the use of pre-crosslinked white EVA, which has been the mainstream in the market, has been unsatisfactory until now, with some problems. Firstly, EVA is higher than POE by an order of magnitude due to the characteristics of materials, water vapor is easy to enter the assembly after long-term aging, free acidic substances are further generated, corrosion exists on welding belts and batteries, and assembly power is affected. Particularly, the single glass component has worse water vapor barrier capability and more serious water vapor permeation condition; in addition, in order to improve the battery conversion efficiency, each battery manufacturer and component terminal continuously innovates the battery technology, the N-type TOPCon battery is or becomes the next mainstream, and the N-type TOPCon battery is more sensitive to acid and water vapor, and the conventional EVA packaging adhesive film is difficult to meet the packaging requirement of the N-type TOPCon battery, and the low-acid packaging adhesive film is urgently needed to meet the packaging requirement of the N-type TOPCon battery. Secondly, due to the generation of free acetic acid, free migration anions and cations can be generated, leakage current is formed under the action of potential difference, PID effect is generated, and the power of the assembly is affected; moreover, the pre-crosslinked white EVA in the market at present is mostly irradiated by using high-energy particle beams, an energy absorption process exists in the irradiation process of the adhesive film, the melting point of the conventional photovoltaic EVA particles is lower, the adhesive film is softened after energy absorption to cause stretching, the wide width of the adhesive film is easy to change, the adhesive film is also sticky after energy absorption and softening, the inside of the adhesive film is easy to adhere under the influence of winding tension, and particularly the adhesion condition is easy to be aggravated after high-temperature transportation in summer. Finally, as the white EVA is added with the white pigment, if overflow to the surface of a battery, a welding strip and a confluence surface occurs, serious appearance problems can be brought, and the overflow to the surface of the battery can influence the power, so that use problems can be brought to customers.

The formula system is optimized in three different modes, so that the water vapor barrier capability of the finished product and the ageing resistance effect of the adhesive film are improved.
