Abstract

PURPOSE:To make the bonding process of solar cells effective by a method wherein a Teflon resin made thread in diameter equivalent to the gap between the solar cells and a solar panel is held between the gap to bond the solar cell module. CONSTITUTION:When solar cells 2 are bonded onto a solar panel 1 using silicon resin bonding agent 6, in order to secure the gap between the solar cells and the solar panel 1, a Teflon resin made thread 9 in diameter equivarent to the gap is held between the solar cells 2 and the solar panel 1 before the bonding process. The resin thread 9 is disposed in tension in the longitudinal direction of solar cell module so that next row of solar cells may be bonded before the bonding agent 6 is completely set making continuous bonding process feasible while facilitating the removal of resin thread 8. Through these procedures, the bonding process of solar cells can be performed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an adhesion method that ensures a gap between a solar cell and a solar panel in the process of adhering a solar cell to a solar panel.

[Conventional technology]

First, a conventional bonding method will be briefly explained using FIGS. 3 and 4. FIG. 4 is a sectional view of FIG. 3.

In the figure, (1) is the solar panel, (2) is the solar cell, +audgff hand, (S) is the solar cell module, and the solar cell (21
f are connected in parallel or in series. (4) is a metal spacer, and (5) is a resin spacer, which is made of the same material as the adhesive in (6). 2) is a weight module in which the weight module in ()) is attached to the rubber sheet in (81) to correct the deformation of the solar cell module.
A mutual gap is ensured.

Next, the adhesion procedure will be explained. Place the resin spacers (5) one by one on the solar panel (1) at the center of the solar cell (21), apply adhesive (6) onto the resin spacer (51), and then attach the metal spacer (
Place 4) on the solar panel (1) between the adhesive +61, place the solar cell module on the appropriate position between the metal spacer (4) and the adhesive (6), and place the 9-layer module on the solar cell module. . The adhesive (6) is allowed to cure for a period of time until the solar cell module no longer deforms.

Remove the metal spacer (4) and move on to the next step of adhesion.

[Problem that the invention seeks to solve]

In this method, it is necessary to grasp several resin spacers (5) with a bottle set and place them on the solar panel (1), and moreover, it is necessary to place them at the center of the solar cell (2), which takes a very long time. praise.

Also, since it is inserted laterally into the metal base + (4!) solar cell module, it cannot be removed until the &layer agent (6) has hardened, resulting in a long wait time for it to harden. There were problems such as the inability to adhere.

This invention was made in order to solve the above-mentioned problems.According to this invention, the gluing work can be performed extremely easily, and moreover, the gluing can be performed continuously, which improves the efficiency of the gluing work. It is something that contributes.

[Means for solving the problem] In the bonding method according to the present invention, a solar cell module is bonded between a solar cell and a solar panel by sandwiching a thread T of Teflon resin with a diameter corresponding to the gap. It is.

〔Example〕

1 and 2 show an example of the bonding method according to the present invention, and FIG. 2 is a sectional view of FIG. 1.

In the figure, (9) is a resin thread, αα is a tensioning tool, and the resin thread (9) is stretched on the solar panel (1).

As a material for the resin thread (9), a Teflon-based resin material (for example, Toyoflon-L manufactured by Toshisha Co., Ltd.) can be used. This resin thread material is not originally commercially available for use in the application of this invention, but the applicant has tried using it.

It is extremely easy to handle, ensuring a gap between the solar panel (11) and the solar cell (21), and the adhesive (
It has been discovered that the adhesive (5) has a property of not adhering to the adhesive (5) when it is cured.

In addition, by making the weight (7) smaller than the reaction force of the stress relief loop of the joint (3) and having a weight that can correct the deformation of the solar cell module, the gap between the solar cells (2) can be reduced. was secured.

Therefore, as shown in Figs. 3 and 4, the resin thread (9) is stretched over the solar panel (1) using the tensioning tool αα, the adhesive (6) is applied, and the solar cell module is placed on it. Once the module is placed on it, it can be easily glued. And since the resin threads are stretched in the vertical direction of the solar cell module, the next row can be glued without waiting for the adhesive (6) to harden, making continuous bonding possible, and removing the resin threads (91) is also extremely easy. It is.

〔Effect of the invention〕

As described above, according to the present invention, the work of adhering solar cells can be efficiently carried out, making a great contribution to the improvement of the two-work process.
