Description
Technical Field
The invention relates to the technical field of packaging adhesive films, in particular to a high-reflection black adhesive film and a preparation method and application thereof.
Background
With the rapid development of photovoltaic power generation technology and application, Building Integrated Photovoltaics (BIPV) has a wide development prospect as a combination point of a building market and a photovoltaic market. The combination of photovoltaic and building is one of the most important fields in future photovoltaic application, and has huge market potential.
Building photovoltaics have certain requirements on the appearance of the module, which makes the black module a very beneficial development in the field of BIPV. At present, black assemblies on the market are basically realized by adopting black frames and black back plates, but for attractiveness, the double-glass assembly which is completely black in appearance is realized through a black film, and the requirement of BIPV is met. However, compared with a conventional transparent component or a ceramic white component, the black component packaged by the black adhesive film has the problems of low initial power, high operating temperature and short service life. The black color has strong absorption to all-band light, and the absorption of near infrared light of 760-1200 nm available for the cell directly causes the temperature of the assembly to rise by more than 5 ℃, so that the generating efficiency of the cell is reduced, and the power is lower than that of a conventional transparent assembly or a ceramic white assembly.
Aiming at the problems of the black assembly, in the prior art, the heat-conducting filler is added into the adhesive film to realize the heat-radiating effect, but the heat-conducting filler such as titanium dioxide or silicon dioxide is less in addition, the heat-radiating effect cannot be achieved, and the appearance is influenced by whitening of the black film due to more addition; the black high-reflectivity back plate is used for realizing light reflection of an infrared band, but a layer of ultraviolet high-cut-off adhesive film is arranged between the back plate and the battery piece, so that certain loss exists in reflected light, and meanwhile, the heat dissipation and the attractiveness of the black back plate are poorer than those of a double-glass black assembly; the infrared region reflection filler is directly added into the black film to realize the reflection of the near infrared region, so that light of 700-1200 nm is reflected to the cell, the heat absorption is inhibited, and the power is improved, but the reflection efficiency is limited due to the defects of modification and single-layer structure of the directly added reflection filler, the reflectivity of the near infrared light can only reach below 50 percent, and the reflectivity of the near infrared light is far less than 70 percent of that of the ceramic white film in the region.
In view of the above, the present invention is particularly proposed.
