Description
Technical Field
The invention relates to the technical field of solar cell manufacturing, in particular to a weather-resistant solar cell back plate and a preparation method thereof.
Background
Solar cells are devices that directly convert light energy into electrical energy through a photoelectric effect or a photochemical effect, and are widely used in military, aerospace, industrial, commercial, agricultural, communication, household appliances, and public facilities. The solar cell back plate is one of solar cell module packaging materials, the main performance of the solar cell back plate is packaging crystalline silicon, the solar cell back plate plays a role in protecting a solar module from natural environments such as water vapor, ultraviolet, temperature, frost and the like, and the photoelectric conversion efficiency and the service life of the solar cell are directly influenced by the quality of the performance of the solar cell back plate.
The solar cell panel is generally a laminated structure, and is formed by laminating a transparent cover plate, a sealant layer, a solar cell sheet, a sealant layer and a solar cell back plate. The solar cell backboard mainly has the advantages that the overall mechanical strength of the solar cell panel is improved, and the influence on the service life of a cell piece caused by the fact that water vapor permeates into the sealing layer can be prevented. Therefore, the solar cell back sheet must be insulated, i.e., have electrical breakdown resistance, aging resistance, weather resistance, and corrosion resistance.
Currently, the conventional solar cell back panel is produced by a multilayer film lamination molding mode, and the commonly used back panel can be divided into a TPT, a TPE, a full PET and a PET/polyolefin structure, wherein T is a polyvinyl fluoride (PVF) film of dupont, usa, and the trade name of T is Tedlar; p is a biaxially oriented polyethylene terephthalate film, i.e., a PET film, also known as a polyester film or a polyester film; e is ethylene-vinyl acetate resin EVA; polyolefin refers to various plastics having a carbon-carbon structure as a main chain. TPT and TPE have weather-resistant fluorine-containing surface materials, so that the weather resistance of TPT and TPE is excellent, but most of the fluorine-containing materials are imported from foreign countries, the price is high, the rear panel with a full PET and PET/polyolefin structure has poor weather resistance, and the requirements of high-end products cannot be met.
Therefore, there is a need for a more efficient method for preparing solar cell back sheet films that are inexpensive and have excellent weatherability.
