Problems solved by technology

However, when the existing cutting method is used to cut solar cells, due to the ductility of stainless steel and copper wires, the copper wires, stainless steel, carbon, etc. are connected to each other, resulting in a short circuit, and the solar cells are cut by The protective film and the battery surface have a strong bonding strength and are not easy to separate
Therefore, there is a problem of extremely high short-circuit rate in the use of solar cells, and the use of laser, sandblasting and etching has no good effect.

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0018] Such as figure 1 As shown, the solar cell sheet cutting method of the present invention comprises the following steps:

[0019] S1. Place the standard solar cell and the protective film on the cutting station, and use a cutter to cut the standard solar cell and the protective film according to the carbon line.

[0020] Wherein, during cutting, the standard solar battery sheet and the protective film are cut vertically according to the carbon line with a cutter.

[0021] S2. Obtain a solar cell unit that meets the specifie...

Abstract

The invention provides a solar cell cutting method, which comprises the steps of S1, placing a standard solar cell and a protective film thereon on a cutting station, and cutting the standard solar cell and the protective film according to a carbon line by using a cutter; S2, acquiring a solar cell unit conforming to the specified dimensions through cutting, and heating a carbon line notch of the solar cell unit; and S3, and stripping a copper wire of the solar cell unit by 0.9mm-1.0mm after heating. The solar cell cutting method provided by the invention can significantly reduce the short-circuit rate of the cut solar cell. Specifically, voltage of a solar cell acquired according to the cutting method provided by the invention can reach over 0.5V under 3800lux, and the yield of the solar cell can be maintained at 97%.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for cutting solar cells. Background technique [0002] In the field of solar cells, it is necessary to cut the produced standard solar cells so that their dimensions meet the needs of use. However, when the existing cutting method is used to cut solar cells, due to the ductility of stainless steel and copper wires, the copper wires, stainless steel, carbon, etc. are connected to each other, resulting in a short circuit, and the solar cells are cut by The protective film adheres strongly to the surface of the battery and is not easy to separate. Therefore, there is a problem of extremely high short-circuit rate in the use of solar cells, and the use of laser, sandblasting and etching has no good effect. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0004] The object of the present inv...
