Problems solved by technology

[0006] In order to match the beautiful appearance of the car, the car sunroof is generally designed in a streamlined arc. At present, most of the mass-produced car solar sunroofs on the market are crystalline silicon components. Ordinary crystalline silicon cells have very poor flexibility and are extremely flexible when bent Easy to break, when packaged into a curved car sunroof, crystalline silicon cells are prone to breakage
In addition, due to the limitations of production equipment and technology, it is impossible to carry out diversified production. Generally, a production line can only produce products with one size or similar specifications. Market popularization of solar car sunroof

Embodiment 1

[0030] Such as figure 1 , figure 2 The solar sunroof shown includes a flexible solar cell sheet 1, a skylight glass 4 and a flexible encapsulation layer 3, and the two sides of the flexible solar cell sheet 1 are respectively bonded with the skylight glass 4 and the flexible encapsulation layer 3 via an encapsulation adhesive layer 2. bonded to form an integral stack, and then use the sealing strip 7 to seal and protect each stack from the side. The current generated by the flexible solar cell 1 is collected through the bus bar 5 placed above it, and then connected to the The junction box 5 on the side of the laminate.

[0031] In this embodiment, the flexible solar cell 1 adopts a copper indium gallium selenium flexible solar cell with a stainless steel substrate. layer, CIGS absorber layer, molybdenum back conductive layer and ultra-thin stainless steel substrate. The encapsulation adhesive layer 2 is made of EVA adhesive film, optionally, it can also be light-transmitti...

Embodiment 2

[0035] Such as image 3 , Figure 4 The solar sunroof shown differs from Embodiment 1 in that: the flexible solar cells 1 and the flexible encapsulation layer 3 are integrated.

[0036] In this embodiment, the flexible solar cell 1 uses an amorphous silicon solar cell with a flexible glass substrate. The cell is transparent, and the flexible glass used as the substrate is also transparent and has a certain mechanical Strength, the substrate can replace the flexible encapsulation layer 3 and the corresponding encapsulation adhesive layer 2, which greatly simplifies the process flow and saves production costs. The current generated by the cell is collected through the bus bar 5 placed above the flexible solar cell 1 , and then connected to the junction box 6 .

[0037] The solar skylight can be manufactured according to the following process:

[0038]Place the skylight glass 4, the encapsulation adhesive layer 2, and a piece of flexible solar cell 1 with a suitable size and s...

Abstract

Disclosed in the invention is a solar sunroof comprising flexible solar cells, a piece of sunroof glass, and a flexible packaging layer. The two sides of the flexible solar cells are bonded with the sunroof glass and the flexible packaging layer by packaging glue layers. Because of advantages of high flexibility, good light and thin properties, and good light transmitting of the flexible packaging layer, defects that the existing solar sunroof cell is easy to break and is not suitable for a curved-surface and specially-shaped assembly can be effectively overcome; and the light transmitting performance of the sunroof is guaranteed. Meanwhile, because the flexible solar cells can be cut randomly, the adaption of the product diversification can be substantially enhanced. Moreover, the solar sunroof has advantages of light structure, low cost and wide application prospects.

Description

technical field [0001] The invention relates to a sunroof that can utilize solar energy and belongs to the field of photovoltaic applications. Background technique [0002] Car sunroofs have a history of more than 100 years. In the United States, 400,000 vehicles are equipped with sunroofs every year, and in South Korea, 50,000 vehicles are equipped with sunroofs every year. The number of cars in China is also increasing. The car sunroof can facilitate the air circulation in the car, the ventilation is soft, and the air in the car is fresh, especially the fresh air in the upper layer can keep the driver's mind clear, make driving safer and more reliable, and bring comfortable and healthy enjoyment to car owners. It is favored by many consumers. of favor. [0003] Today, with the continuous development of automobile technology, various electrical equipment with different functions are integrated into the car. Some electrical appliances work when the car is started, and some ...
