Abstract

The invention belongs to the technical field of PVDF thin films, and specifically relates to a high-permeability PVDF thin film material and a preparation method thereof, a TPT backing film, a TPE backing film and a solar cell panel. The high-permeability PVDF thin film material includes, by weight percentage content, 60-85% of PVDF, 5-30% of PMMA, 0-20% of a flexibilizer, 0-0.5% of an anti-oxidant, and 0-0.5% of an ultraviolet absorbent. The provided high-permeability PVDF thin film material has high light transmittance; and the made backing films can enhance the light transmittance of environmental reflected light, and therefore, the electricity generation power of the solar cell panel can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of PVDF films, and in particular relates to a high-permeability PVDF film material, a preparation method thereof, a TPT back film, a TPE back film and a solar battery panel. Background technique [0002] The solar cell back film is located on the back of the solar cell panel. As a photovoltaic packaging material that is directly in contact with the external environment in a large area, it must not only have a protective function, but also have a reliable insulation performance of 25 years, and resistance to long-term aging (humid heat, dryness, etc.) heat, ultraviolet), water vapor barrier and other properties. Solar cell back film, EVA film, crystalline silicon cell, glass, frame and junction box are assembled into a crystalline silicon solar cell panel. According to the production process, the back film can be divided into a laminated back sheet and a coated back sheet. The laminated film backsheet is pr...
