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.
The present disclosure discloses a low-water-vapor-permeability polyolefin-elastomer film and its preparation method. The film comprises: 50-100 mass parts of a matrix resin, 0-40 mass parts of a modified resin, 0.001-2 mass parts of an activator, 0.1-3 mass parts of an organic peroxide, 0.02-5 mass parts of an assistant cross-linker, 0.02-2 mass parts of a silane coupling agent, 0.005-2 mass parts of a light stabilizer, and 0-20 mass parts of a water blocking filler. In the present disclosure, by adding the modified resin and the activator that have an active group, a cross-linking degree and a cross-linking density of the film are improved, and a water-vapor permeability is reduced; by adding the water blocking filler, the water blocking property of the film is further improved, thereby ensuring reliability of the assembly, and prolonging service life of the assembly.

Disclosed in the present invention is a low fluidity encapsulant film, obtained by evenly mixing 100 parts by weight of base material having a melt index of 0.2-9 g/10 min, 0.1-5 parts by weight of peroxide-based crosslinking agent, 0.1-5 parts by weight of auxiliary crosslinking agent, 0.1-3 parts by weight of tackifying agent, 0-5 parts by weight of hindered amine light stabiliser, 0-2 parts by weight of ultraviolet light absorbing agent, and 0-40 parts by weight of pigment, adding same to an extruder, and extruding into a film by means of a T-shaped flat mould. The encapsulant film can reduce the risk of a cell of a photovoltaic module shifting during a laminating process, and prevent the layer of pigment-containing encapsulant film on the back of the module from covering the front surface of the cell during high-temperature lamination as a result of good fluidity. Due to the use of a thermal pre-crosslinking method, the acid content of the encapsulant film is significantly reduced compared to using a radiation crosslinking method, and there is less corrosion of the solder strips, bus bar, and cells of the module, so that the high power generation performance of the photovoltaic module can be maintained for longer.

A highly reflective gain type photovoltaic packaging adhesive film and usage are provided. The packaging adhesive film is composed of an packaging layer and a reflecting layer, wherein the packaging layer has a thickness of 200 to 500 μm, and is made by mixing a first primary resin, a modified auxiliary, an ultraviolet auxiliary, an anti-thermal oxidation ageing agent and an initiator and melting and coat casting the same at 60° C to 200° C to form a film; and the reflecting layer has a thickness of 5 to 200 μm and is made by mixing a second primary resin, an auxiliary resin, a first filler, a second filler, modified auxiliary, a diluent and an ultraviolet auxiliary, an anti-thermal oxidation ageing agent and an initiator and coating the same on the surface of the packaging layer and curing the same at 30°C to 150°C. With a simple preparation process, a low cost, and an excellent product performance, the packaging film not only provides an effective gain effect for a double-sided crystal silicon battery module, but also provides a basis for optimizing the cost of the gain-type packaging material for a single-sided crystal silicon battery module, and at the same time, providing a guarantee for reliability of crystal silicon photovoltaic modules in long-term outdoor application.
