Problems solved by technology

[0003] The present invention aims at the technical problems of low photoelectric conversion efficiency, short service life and poor cleaning effect of solar cell components in the prior art, and provides a self-cleaning solar cell component with high conversion rate. The outer surface is coated with a hydrophobic anti-reflection film, and the rain or dew falling on the tempered glass will take away the dust when it rolls down, so that the glass surface always has a high light transmittance, thereby improving the photoelectric conversion rate of the module. The overall mechanical strength is high, with excellent anti-corrosion, windproof, waterproof, dustproof and hailproof capabilities, and long service life

Embodiment 1

[0016] Example 1: like figure 1 and 2 As shown, a self-cleaning solar cell module with high conversion rate, including tempered glass 1, EVA film 3, anti-reflection film 4, monocrystalline silicon solar cells 5, EVA film 6, back plate 7, aluminum alloy The frame 8 and the DC junction box, the tempered glass 1, the EVA film 3, the anti-reflection film 4, the monocrystalline silicon solar cell 5, the EVA film 6 and the back plate 7 are sequentially laminated to form a component laminate. The aluminum alloy frame and silica gel seal and package the component laminate, and the monocrystalline silicon solar cell 5 is electrically connected to the DC junction box after being welded and connected to the bus bar, and the solar cell module is generated through the DC junction box. The electrical energy is output to the external system, and then the electrical energy is output to the user or stored for reuse through components such as wires, controllers, inverters or batteries. The ...

Embodiment 2

[0017] Example 2: As an improvement of the present invention, the aluminum alloy back plate adopts 5052 aluminum alloy plate as the substrate, and an anodized film of 15-20um is electroplated on both sides of the substrate. This kind of aluminum alloy back plate has good corrosion resistance , the corrosion effect on the back plate after being exposed to the air for 25 years on one side is basically negligible, and because its thermal conductivity (144w / (m.k)) is much larger than the heat conduction system of the traditional TPT back plate, the battery assembly can be The heat is exported more effectively, the temperature of the solar cell module is reduced, the efficiency of the module is improved, and the service life requirement of the module is also met. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0018] Example 3: As an improvement of the present invention, the content of iron in the raw materials for preparing the tempered glass 1 is 80--120ppm. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a self-cleaned solar cell assembly with a high conversion rate. The self-cleaned solar cell assembly comprises toughened glass, an EVA adhesive film, a single crystalline silicon solar cell slice, an EVA adhesive film, a backplane, an aluminum-alloy frame, and a DC junction box, and is characterized in that the toughened glass, the EVA adhesive film, the single crystalline silicon solar cell slice, the EVA adhesive film, and the backplane are successively laminated to form an assembly laminated member; the assembly laminated member is subjected to sealed packaging by using the aluminum-alloy frame and silica gel; the single crystalline silicon solar cell slice is electrically connected with the DC junction box after being welded on a busbar; the toughened glass is low-iron ultra-white toughened glass with a light-receiving surface plated with a hydrophobic antireflection film; the backplane is an aluminum-alloy backplane with double surfaces plated with anode oxide films; a small polyester film is arranged between the aluminum-alloy backplane and the busbar exposing the upper EVA adhesive film; and water leakage holes are arranged on both ends of a long side of the aluminum-alloy frame.

Description

technical field [0001] The invention relates to a solar cell assembly, in particular to a solar cell assembly with high conversion rate and self-cleaning function. Background technique [0002] As a product of new clean and renewable energy, solar cell modules have brought huge benefits to mankind. With the continuous development of technology, the improvement of solar light energy conversion efficiency has made this type of product further enter the daily life of thousands of households middle. The photoelectric conversion rate is one of the most important performances of solar cell modules. At present, all kinds of solar cell modules on the market have some quality problems or hidden dangers, such as: EVA yellowing, module delamination, and junction box burnout. This is because solar battery modules are generally installed in the open air, and rainwater and dew often accumulate in the frame. The battery panel unit is eroded by rainwater and dew for a long time, and its se...
