Embodiment Construction

[0025] Depend on Figure 1-4 It can be seen from the shown embodiment that the crystalline silicon solar cell string 1 and the EVA film 2 bonded on the upper surface of the substrate are multi-layered, the substrate is a fiberboard, and the lower surface of the fiberboard is provided with the crystalline silicon solar cell string 1. The power output circuit 8 connected to the negative pole, the fiberboard has a wire hole 12 to pass through the positive and negative power lines of the solar cell string, and the hot melt adhesive film 3 and the bottom textile fabric 4 are bonded sequentially under the fiberboard, and the hot melt adhesive The film 3 and the bottom textile fabric 4 are provided with openings 10 for the power output circuit; the EVA film 2, the light-transmitting film 5 and the top textile fabric 11 are sequentially bonded above the crystalline silicon solar cell string 1, and the top textile fabric 11 leaves a gap with solar energy. The solar receiving holes 6 ma...

Abstract

The invention discloses a solar cell module and a production method thereof, and belongs to the technical field of solar cells. The solar cell module is of a multi-layer structure and comprises a crystalline silicon solar cell string adhered on the upper surface of a glass fiber board, a power output circuit connected with positive and negative electrodes of the crystalline silicon solar cell string is arranged on the lower surface of the glass fiber board, a hot melt adhesive film and a bottom woven fabric are adhered under the glass fiber board in sequence, and an EVA (ethylene-vinyl acetate) film, a light-transmitting film and a top woven fabric are adhered above the crystalline silicon solar cell string in sequence. The solar cell module production method includes sequentially placing the materials into a heating device for preheating, after the EVA film and the hot melt adhesive film are molten, placing the molten EVA film and hot melt adhesive film in a vacuum laminating device, adhering the parts together by the aid of viscidity of the molten EVA film and hot melt adhesive film, and packaging to form a solar power supply. The solar cell module has the advantages of light weight, portability, simple production process, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of solar cells. Background technique [0002] Most of the packaging materials for crystalline silicon solar cells use tempered glass, EVA and waterproof back sheets, and aluminum alloy frames are installed on the four edges. Crystalline silicon solar cells packaged with this material are suitable for large-scale ground power stations and roof power generation installations. Requirements It has a certain ability to resist wind load and snow pressure, so it is heavy in weight and large in area; some are packaged with resin glue, but the resin glue requires a long curing and molding time, and the weather resistance of the resin glue is poor. , easy to turn yellow and crack. [0003] With the continuous development of electronic consumer products, such as smart phones, tablet computers, etc., the functions are constantly enriched, and the demand for electric energy is also increasing. The technology and proces...
