Embodiment 1

[0019] A laminated solar cell module, consisting of a surface layer 1, an upper ethylene-vinyl acetate copolymer layer 2, a solar cell layer 3, a lower ethylene-vinyl acetate copolymer layer 4 and a backsheet layer 5, stacked in sequence from top to bottom Cloth, encapsulation structure, the surface layer 1 is a polyvinyl fluoride composite film, and the back plate layer 5 is an epoxy resin board.

[0020] The method for preparing the above-mentioned laminated solar cell module includes the following steps: a. Put the tempered glass on the workbench at room temperature of 25°C, spread a high-temperature cloth, and spread a layer of polyvinyl fluoride composite film on the high-temperature cloth in turn and a layer of ethylene-vinyl acetate copolymer; b. take an epoxy resin plate, spread a layer of ethylene-vinyl acetate copolymer on it, and then fix the welded battery sheet on the ethylene-vinyl acetate copolymer; c . Lay the epoxy resin plate with the battery sheet fixed on t...

Abstract

A laminated solar battery pack comprises a surface layer, an upper ethylene-vinyl acetate copolymer layer, a solar battery layer, a lower ethylene-vinyl acetate copolymer layer and a back plate layer, which are sequentially laminated and arranged from top to bottom and are packaged together, wherein the surface layer is a polyvinyl fluoride composite film; and the back plate layer is an epoxy resin plate. The small solar battery pack can be widely used in the field of solar products, such as solar table lamp, solar flashlight, solar mobile phone charger and the like, to improve the aging resistance and prolong the service life of the products.

Description

1. Technical field [0001] The invention belongs to the field of new energy photovoltaic power generation, and in particular relates to a laminated solar cell module and a preparation method thereof. 2. Background technology [0002] Existing technology: Due to the increasingly severe global energy crisis and environmental problems, people's demand for new energy and non-polluting renewable energy is becoming more and more urgent. Solar photovoltaic power generation is a promising technology in new energy and renewable energy. field. [0003] The most basic components of solar photovoltaic power generation are solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. A solar panel composed of one or more solar cells is called a photovoltaic module, or a solar cell module. A solar cell module is a device that converts solar energy into electrical energy. It has various installation forms, is safe and pollution-free, an...
