Problems solved by technology

However, the method of recycling and reusing the unqualified finished monocrystalline silicon cells after sintering has not been reported yet.
At present, the usual processing method for these unqualified monocrystalline silicon cells is to sell them at half the price of qualified monocrystalline silicon cells or treat them as fragments. Most of them are not recycled and reused, which increases the production cost of enterprises and causes resources waste of

Embodiment approach

[0027] The present invention also provides a solar cell spray electrode removal method based on the above-mentioned solar cell electrode removal device, one embodiment of which includes the following steps:

[0028] Step S1 : fix the solar cell 11 with the surface to be removed facing downward on the suction cup 20 , and control the rotation of the solar cell 11 through the suction cup 20 .

[0029] Step S2: Adjust the flow rate of each nozzle 31 on the liquid spraying device 30 through each valve of the liquid spraying device 30, and spray the electrode corrosion solution upwards to the corresponding position on the surface to be removed of the electrode of the solar cell sheet 11 through the above-mentioned multiple nozzles 31.

[0030] Optionally, in step S2, the method for removing the sprayed electrodes of solar cells controls the flow rate of the nozzles by operating the solenoid valves 33 provided on the delivery pipes 32 of the nozzles 31 .

[0031] In the above-mentio...

Abstract

The invention relates to a solar cell panel electrode removing device and a solar cell electrode removing method. The solar cell panel electrode removing device comprises a suction cup and a liquid spraying device, wherein the suction cup is used for fixing a solar cell panel and controlling the solar cell panel to rotate when the surface, with electrodes to be removed, of the solar cell panel faces down; the liquid spraying device is placed below the suction cup and comprises a plurality of nozzles and a plurality of valves, each nozzle is used for spraying an electrode corrosive liquid upwards to a corresponding position on the surface, with electrodes to be removed, of the solar cell panel, the plurality of valves are in one-to-one correspondence with the plurality of nozzles, and each valve is used for controlling electrode corrosive liquid spraying flow of the nozzle corresponding to the valve. The solar cell panel electrode removing device and the solar cell panel electrode removing method have the advantages of having good electrode removal uniformity and being capable of improving product quality.

Description

technical field [0001] The invention relates to a solar cell electrode removal device and method, in particular to a solar cell electrode removal device and method. Background technique [0002] In the production of photovoltaic monocrystalline cells, various unqualified monocrystalline silicon cells will be caused due to occasional shaking of equipment or problems in other process steps. These unqualified monocrystalline silicon cells can account for 3% of the daily production of enterprises. The ratio affects the qualified rate of finished products to a certain extent. [0003] The production process steps of photovoltaic monocrystalline cells are as follows: starting from the selection of qualified original silicon wafers, making a layer of suede on the surface of the silicon wafers through alkali corrosion, which can reduce light reflection, and then performing phosphorus diffusion to form a phosphorus diffusion layer (N-type layer ), then remove the phosphorus diffusio...
