Abstract
The invention provides an adhesive film, a composition for forming the adhesive film, a photovoltaic module and laminated glass. The composition for forming the adhesive film comprises ethylene copolymer matrix resin, an amide organic matter, a metal oxide and / or a metal hydroxide, wherein the metal oxide is one or more selected from the group consisting of aluminum oxide, calcium oxide, zinc oxide, barium oxide, magnesium oxide, zirconium oxide, titanium oxide, tin oxide, vanadium oxide, antimony oxide, tantalum oxide, niobium oxide, layered transition metal oxide, and ZnO-doped Al2O3, CaO / SiO2-doped Al2O3, MgO-doped Al2O3, SiO2-doped ZrO2 and TiO2-doped ZrO2 which have been subjected to doping treatment; and the metal hydroxide is one or more selected from the group consisting of calcium hydroxide, magnesium hydroxide, zinc hydroxide, aluminum hydroxide, ferric hydroxide and barium hydroxide. The adhesive film formed by the composition has good anti-PID effect, photoelectric conversion efficiency and packaging performance.
Description
technical field [0001] The invention relates to the field of photoelectric conversion devices, in particular to an adhesive film, a composition forming it, a photovoltaic module and laminated glass. Background technique [0002] Photoelectric conversion refers to the conversion of solar energy into electrical energy through the photovoltaic effect. Commonly used electronic devices (photoelectric conversion devices) that can realize the above photoelectric conversion process include but are not limited to solar cells (such as crystalline silicon cells, amorphous silicon cells, cadmium telluride cells, copper indium gallium tin cells, perovskite cells), Liquid crystal panels, electroluminescence devices, plasma display devices, sensors, etc., are usually sealed by one or more layers of polymer materials, and the sealing materials are bonded to the upper and lower substrates to form a complete electronic device module. For example, crystalline silicon solar cell components are...
