Abstract

The invention relates to a high-fluoride mixcrystal coating solar-energy photovoltaic cell back film and a manufacturing method thereof, which belong to the technical field of solar-energy cell panel back films. The high-fluoride mixcrystal coating solar-energy photovoltaic cell back film comprises seven layers of structures which are sequentially arranged from top to bottom, wherein a first high-fluoride mixcrystal coating is coated between the lower surface of a first basic layer and the upper surface of a second basic layer, a second high-fluoride mixcrystal coating is coated between the lower surface of a third basic layer and the upper surface of a fourth basic layer, and a PET (polyethylene terephthalate) layer is coated between the lower surface of the second basic layer and the upper surface of the third basic layer. In the manufacturing method, the solar-energy photo-voltaic cell back film with seven layers of structures is manufactured by adopting an advanced high-fluoride mixcrtstal interconnection and penetration integration technology, a plasma titanium silicide nano-processing technology and a high-precision unrippled coating technology, the integral vacuum thermoforming of the solar-energy photo-voltaic cell back film, an EVA (ethylene vinyl acetate) sealing adhesive, a solar cell sheet and high-transmittance iron-free glass is carried out for 15 minutes, and the forming temperature is 135 DEG C. A formed assembly conforms to the performance requirement of a photovoltaic power generation device, and the service life can be more than 25 years.

Description

technical field [0001] The invention belongs to the technical field of solar panel back film, and in particular relates to a high fluorine alloy coated solar photovoltaic cell back film and a manufacturing method thereof. Background technique [0002] Solar energy is an inexhaustible clean energy in nature. In recent years, the utilization of photoelectric conversion solar energy has made great progress, technology has continued to improve, and the market has expanded rapidly. Since the photoelectric conversion efficiency of silicon solar cells is higher than that of other types of solar cells, it has developed rapidly. In particular, solar panels made of solar cell backsheets combined with polycrystalline silicon solar cells have gradually become the mainstream of the market. [0003] As a green alternative to conventional methods of electricity production, photovoltaic cell modules are used to generate electricity from sunlight. Photovoltaic modules are assembled from var...
