Problems solved by technology

[0003] However, when the solar cells using the above-mentioned photovoltaic glass are operated outdoors, after a few months or a few years, some batteries have the problem of power attenuation. There are many reasons for the power attenuation. One of the important reasons is the photovoltaic glass. The transmittance of the AR coating decreases
The anti-reflection film in the prior art is a silicon-based film, which has two characteristics: one is porous, the film contains a large number of pores, and the pore structure is the basis of optical anti-reflection; the other is hydroxyl, and there are a large number of hydroxyl groups on the surface of the silicon-based film. , the hydroxyl group makes the anti-reflection film very easy to absorb moisture and pollutants in the environment, especially the adsorbed water and pollutants are held in the pores, which are difficult to remove, and accumulate over time, which makes the anti-reflection film devitrify and pollute, reducing the penetration of sunlight rate, resulting in power attenuation

Embodiment 1

[0033] Such as Figure 1-4 As shown, a processing device for photovoltaic glass, which includes a first turner 2, a first conveyor belt 21, a spraying machine 3, and a second turner 4, which are sequentially arranged on the end side of the lower stage 1 of the tempering furnace. , the second conveyor belt 41, the vacuum chamber 5 and the washing machine 6. A process gas tank 7 , a compressed nitrogen tank 8 and a vacuum pump 9 are also communicated with the vacuum chamber 5 through pipelines.

[0034] The first film turning machine 2 includes a base 20 arranged below one side of the tempering furnace lower table 1, a vertically distributed cylinder 26 is fixedly connected to the base 20, and the output shaft 22 of the cylinder 26 The end is fixedly connected with a frame 27 distributed along the width direction of the tempering furnace lower table 1, and a rotating shaft 23 distributed along the width direction of the tempering furnace lower table 1 is uploaded on the frame 2...

Embodiment 2

[0053] Adopt the same processing device of a kind of photovoltaic glass as in Example 1 to process (therefore, the specific structure of a processing device of photovoltaic glass is not repeated here), that is, a processing method of photovoltaic glass, which includes the following steps : (1) The suction cup arm 24 of the first film turning machine 2 rotates 90 degrees to the left with the rotation axis 23, and the telescopic rod 22 descends, so that the suction cup 25 contacts and absorbs the anti-reflection coating surface of the photovoltaic glass, and then rotates the rotation axis 23 to The right side rotates 180 degrees, the suction cup 25 falls between the two parallel timing belts of the first conveyor belt 21, and the telescopic rod 22 continues to descend, so that the anti-reflection coating surface of the photovoltaic glass 10 contacts the first conveyor belt 21, and the suction cup desorbs. The bottom surface of the photovoltaic glass 10 falls on the first conveyor...

Abstract

The invention provides a photovoltaic glass processing device and processing method, which is characterized in that it includes a first turning machine (2), a spraying machine (3), a second turning A chip machine (4), a vacuum chamber (5) and a cleaning machine (6), and a process gas tank (7), a compressed nitrogen gas tank (8) and a vacuum pump (9) are connected to the vacuum chamber (5). Through the processing steps of flipping, spraying, flipping, replacing hydroxyl groups, and then cleaning the photovoltaic glass, the surface hydroxyl groups in the pores of the photovoltaic glass antireflection film are removed, and the moisture and pollutants in the environment are avoided due to the hydroxyl group adsorption. The sunlight transmittance of photovoltaic glass decreases, which causes the problem of power generation attenuation of photovoltaic glass.

Description

Technical field: [0001] The invention relates to the technical field of photovoltaic glass, in particular to a processing device and a processing method of photovoltaic glass. Background technique: [0002] The surface of photovoltaic glass in the prior art is coated with anti-reflection film, the purpose is to increase the transmittance of sunlight and improve the output power of photovoltaic cells. The processing method of anti-reflection film is: first coat the film on the surface of photovoltaic glass, and then The surface of the glass is sent upwards into the tempering furnace, heated and quenched, and finally the photovoltaic glass coated with an anti-reflection film is obtained on the lower stage of the tempering furnace. [0003] However, when the solar cells using the above-mentioned photovoltaic glass are operated outdoors, after a few months or a few years, some batteries have the problem of power attenuation. There are many reasons for the power attenuation. One ...
