Problems solved by technology

This method is suitable for car sunroofs with a low degree of curvature. When the size of car sunroofs becomes larger and larger, especially the emergence of dome-shaped sunroofs, the degree of curvature of the sunroof glass is greatly increased. The joint will cause the edge of the thin glass to be cracked due to great stress, or cause the central part of the skylight to be insufficiently bonded to the glass, causing air bubbles or hollowing

Embodiment 1

[0028] Embodiment 1: Manufacture a solar sunroof of opaque single-layer skylight glass.

[0029] The car sunroof glass has a surface curvature consistent with the roof, and the thickness of the sunroof glass is 4mm, which is tempered glass;

[0030] Cut the 0.7mm thick Soda lime glass to the size of the car sunroof, and the edge is slightly indented by 3~5mm from the car sunroof glass;

[0031] Carry out edging treatment on the above-mentioned glass, place the treated glass in a heating mold, heat to 550~650 degrees to soften the glass, wait for the glass to be completely bonded to the mold, and start cooling until room temperature;

[0032] Take out the formed thin glass, and deposit the first electrode transparent conductive film boron-doped zinc oxide in the coating equipment. The deposition thickness is 1500~2500nm, and the sheet resistance is 8~15ohm / sq; Coating, usually prolongs the glass preheating time by more than 1 times (compared with flat glass coating), to ensure...

Embodiment 2

[0035] Embodiment two: light-transmitting single-layer skylight glass, such as figure 2 As shown, it is similar to the structure of Embodiment 1, and includes a skylight glass 1, an adhesive layer 2, a second electrode 3, a photoelectric conversion layer 4, a first electrode 5, and an ultra-thin glass substrate 6 from the outside to the inside. However, the coating on the ultra-thin glass substrate has transmission lines 7 .

Embodiment 3

[0036] Embodiment 3: Manufacture sandwich solar skylight.

[0037] The car sunroof glass has the same surface curvature as the roof. There are two pieces of sunroof glass. The sunroof is a laminated glass structure. The thickness of the two pieces of glass is 2.1mm, which is semi-tempered glass;

[0038] Cut the 0.4mm thick Soda lime glass to the size of the car sunroof, and the edge is slightly indented by 3~5mm than the car sunroof glass;

[0039] Carry out edging treatment on the above-mentioned glass, place the treated glass in a heating mold, heat to 550~650 degrees to soften the glass, wait for the glass to be completely bonded to the mold, and start cooling until room temperature;

[0040] Take out the formed thin glass, and deposit the first electrode transparent conductive film boron-doped zinc oxide in the coating equipment. The deposition thickness is 1500~2500nm, and the sheet resistance is 10~20ohm / sq; Coating, usually prolongs the glass preheating time by more t...

Abstract

The invention discloses a curved surface solar energy automobile skylight and a manufacture method for the same, and particularly relates to a curved surface solar energy automobile skylight and the manufacture method for the same. The curved surface solar energy automobile skylight has curved-surface-shaped single layer or double-layer skylight glass; a solar energy battery sheet is composited on the inner side of the single layer skylight or between the double-layer glass; the solar energy battery sheet comprises a super-thin glass substrate, the curved surface shape of which is identical to or similar to the skylight glass; a first electrode, a photoelectric conversion layer and a second electrode are successively plated on the super-thin glass substrate; and the solar energy battery sheet is adhered to the skylight glass through a adhesive layer. The curved surface solar energy automobile skylight and the manufacture method for the same disclosed by the invention can greatly reduce the cracking and damage caused by the strain force in the process of lamination, can improve the yield and can reduce the manufacture cost.

Description

technical field [0001] The invention relates to a car sunroof structure and a manufacturing method with solar power generation function, in particular to a curved solar car sunroof and a manufacturing method thereof. Background technique [0002] The solar roof system is the product of the combination of solar power generation technology and the automobile industry. Embed solar cells or solar modules into the area on the roof of the car that receives sunlight, which can convert sunlight into electrical energy to support some functions that still require electrical energy when the engine stops working, such as interior ventilation in high temperature weather , Air purification inside the car under polluted environment, car security system, car refrigerator, etc., thereby reducing the dependence of these functions on the battery and reducing the loss of the battery. With the rise of electric vehicles and the development of solar technology, it has become a reality to use the ...
