Description
Technical Field
The invention relates to the field of solar dual-glass cell production.
Background
The lamination process is a process of evacuation, extrusion, design, and half dual glass assembly leads to leading out wire hole position POE volume of gluing to lack owing to the problem in structural design itself, very easily causes the leading out wire hole bubble in the lamination process. In the field of manufacturing of the double-glass photovoltaic module, particularly in the production process of the half-sheet module, the total thickness of the double-glass is about 5mm, bubbles in an outlet hole are a long-standing problem, the problem is more and more prominent along with the continuous popularization of the double-glass, and the problem cannot be solved in the actual production by a conventional plugging method.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: how to eliminate or reduce the bubbles at the hole positions of the dual-glass outgoing lines.
The technical scheme adopted by the invention is as follows: a method for solving the problem of bubbles at the position of a dual-glass lead hole is characterized in that a high-temperature adhesive tape with bumps is adhered to the lead hole before lamination.
Each salient point of the high-temperature adhesive tape is a semi-sphere, and when the high-temperature adhesive tape is adhered, a section with one salient point is intercepted, and the salient point is buckled in an outlet wire hole.
The diameter of the salient point is equal to the aperture of the outlet hole.
The invention has the beneficial effects that: bubbles of the outgoing line hole of the half-piece double-glass photovoltaic assembly are eliminated; the product quality of half double-glass photovoltaic module is improved.

FIG. 2 is a schematic view of a high temperature adhesive tape construction;
wherein, 1, glass, 2, POE adhesive film, 3, high-temperature adhesive tape, 4 and an outlet hole.
Detailed Description
1. The photovoltaic module lamination mainly has the functions of vacuumizing, pressure and temperature so as to eliminate air bubbles in the module, and the adhesive film can perform crosslinking reaction at a proper temperature to form a compact three-dimensional structure;
2. the reason that the half double-glass photovoltaic module outgoing line generates bubbles is the existence of a local single-layer adhesive film, and the existence of the back glass is caused by the fact that the position space cannot be compressed by lamination, so that local adhesive shortage is caused;
3. the problem can be well solved by reducing the vacuum space at the position in the laminating process, so that the problem can be solved by adhering the high-temperature adhesive tape with a convex point in the middle on an outlet hole;
4. the high temperature resistant tape can be stable at least at 300 ℃ (e.g., glass teflon tape);
5. the diameter of the salient point is consistent with the aperture of the back glass lead wire, and the diameter of the back glass lead wire can be controlled to be +/-2 mm in practice;
6. the height of the salient points in the embodiment is 2mm, and can be controlled to be 2-4mm in practice.
