Problems solved by technology

[0005] However, there are the following problems in the solar cell panel for automobiles with the above structure: (1) Since its surface is a toughened glass layer, in order to ensure a certain strength, the thickness of the toughened glass needs to reach about 5mm, so that the weight of a solar cell module is 25Kg left and right, thus greatly increasing the weight of the car, which not only increases energy consumption, but also is inconvenient to use; (2) In order to ensure the appearance of the car, the tempered glass is made into the same hyperboloid structure as the roof cover of the fixed model car, so Different molds need to be made for different models, so the cost is high; (3) Since crystalline silicon is directly made on the roof cover, when some crystalline silicon batteries fail, they cannot be replaced, resulting in the failure of the entire battery panel

Embodiment 1

[0033] See attached Figure 1~4 As shown, a solar panel for automobiles includes a polyethylene terephthalate film 1, a crystalline silicon battery 2, a glass fiber 3, and a flexible epoxy resin board 4 from top to bottom. All are glued and fixed by adhesive 5. The adhesive is ethylene-vinyl acetate copolymer. The crystalline silicon cell is a quarter dicing of a crystalline silicon cell. The front and back sides of the flexible epoxy resin board are provided with contacts 6 corresponding to the positions of each row of crystalline silicon cells, and are electrically connected to the crystalline silicon cells on the upper side.

[0034] In the above, the glass fiber has the following functions: (1) Since the polyethylene terephthalate film, crystalline silicon battery, glass fiber and soft epoxy resin board are all bonded and fixed by adhesive, Before solidification, all the gas needs to be exhausted, so the glass fiber can provide a path for the gas to be exhausted; (2) When ...

Abstract

The invention discloses a solar energy battery panel for an automobile, comprising a polyethylene glycol terephthalate film, a crystalline silicon battery, glass fiber and a soft ethoxyline resin plate from top to bottom sequentially, each layer is adhered and fixed by adhesive. The thickness and the weight of the solar energy battery panel for the automobile are less, and the solar energy battery panel for the automobile can be adhered and integrated with the top of the automobile.

Description

Technical field [0001] The invention relates to a solar cell, in particular to a solar cell panel for automobiles. Background technique [0002] In recent years, with the vigorous development of the solar energy industry, solar panels that combine solar cells and automobiles have appeared, and are generally installed on the roof of automobiles to charge the automobile batteries. Because solar panels are energy-saving and environmentally friendly, and have low additional costs, they are suitable for industrialization, so they have been widely studied and applied. [0003] The structure of the existing solar panels for automobiles is as follows: from top to bottom, there are tempered glass, crystalline silicon cells and TPT backsheets. Each layer is bonded and fixed by an adhesive, such as ethylene-vinyl acetate copolymer. A solar cell module is fixed with an aluminum frame to form a flat panel, and finally installed on the roof of the car by the aluminum frame. However, since the ...
