Under these circumstances, solar cells are attracting attention as a viable alternative energy source, and as the price of solar cells decreases, the global market size is rapidly increasing.

The solar cell module, which is a key element of the photovoltaic power generation system, can be used semi-permanently with a life span of about 20 years or more, and can be freely manufactured from small to large according to the installation location and size. In such a solar cell module, a thermal bonding process of connecting the solar cells to each other by a power line, that is, a metal electrode, to be modularized is called a tabbing or soldering process. This tabbing process is performed by heating the junction of the metal electrode (ribbon) and the solar cell with a halogen infrared lamp (IR tabbing) or by soldering the worker one by one.

Recently, the demand for thinning of solar cells is high due to the depletion of materials and rising production costs due to the increased demand for silicon.

Accordingly, there is a demand for the development of a tabbing method capable of improving the bonding and bonding uniformity of the solar cell and the electrode and increasing the production efficiency.

In order to achieve the above object of the present invention,

According to one aspect of the present invention,

A block assembly having a first block and a second block coupled thereto, the through-holes formed in a length direction thereof; And

Provided is a tensioning device for guiding an electrode line including a pressing means for providing a tension in an up-down direction to an electrode line disposed in the through hole.

At this time, the pressing means, it is preferable to include a groove formed along the coupling surface of any block in the longitudinal direction and the pressing projection formed in the coupling surface of the other block corresponding to the coupling surface located in the groove.

At this time, the pressing protrusion is preferably formed in a curved surface along the longitudinal direction of the block.

In addition, in the tension device for guiding the electrode line according to an aspect of the present invention, the first and second blocks are fastened by fastening means, and are disposed between one surface of the block and one end of the fastening means exposed to the outside of the block. It is preferable to further include an elastic member.

As described above, in the process of tabbing the solar cell module and the electrode line (ribbon), the tension device for guiding the electrode according to the present invention may prevent the deformation of the electrode and improve the straightness, which may occur during the tabbing process. The failure rate of the solar cell module can be reduced.

Hereinafter, a tension device for guiding electrode lines according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings show exemplary forms of the present invention, which are provided only to explain the present invention in more detail, and thus the technical scope of the present invention is not limited thereto.

In the tabbing process, in a state where the solar cell 1 is loaded on the work table 7, the electrode wires (ribbon, 2-1, 2-2) are pressed onto one or both surfaces of the solar cell 10, and then the laser is pressed. The contact part 6 of the electrode line of a solar cell is joined along a tabbing direction using etc.

Here, the term "tabbing direction" refers to the longitudinal direction of the contact portion of the electrode wire and the solar cell, and by moving the worktable or the like, the laser or the like may sequentially scan and heat the contact portion, and in this case, the tabbing direction may be described above. It is used in the same sense as the longitudinal direction of the assembly.

In this tabbing process, it is most important to maintain the integrity of the electrode line bonded to the solar cell, and the electrode line does not maintain the straightness, especially when deformation occurs in the left and right directions on one surface of the solar cell module. It will cause a defect.
