第1図及び第2図により説明する。An example of a solar cell panel is a super straight type solar cell with the goal of low cost and high reliability. An example of the channel will be explained with reference to FIGS. 1 and 2.

としてブチルゴムが用いられる。That is, a transparent cover glass (11) serves as the structural support for the entire panel, and one side of this cover glass (1) is comprised of solar cells (3) connected in series inside it. A filling material (2) in which strings are embedded is glued. Polyvinyl butyral (hereinafter referred to as PVB) has usually been used as this filling material (2). Filling material (2) A backing material (4) is adhered to the back side of the backside material (4).As shown in FIG.・Vinyl fluoride (
It consists of a three-layer structure of PVF (hereinafter referred to as PVF). This aluminum foil (6) is for preventing water vapor from permeating from the outside. As shown in Figure 1, the periphery of this solar panel is fixed to an aluminum frame (8) that is anodized using an insulating material (force). Butyl rubber is used as a low-cost material that maintains the same properties.

is being developed.
即ち、EVAはP’VBと比較すると次のような利点が
あるからである。That is, EVA has the following advantages when compared with P'VB.
(1)材料費がKVAO方が安く現在PVBの杓子の値

(2)拐料のプロセッシングの場合にもEvAの方が簡
単である。(1) KVAO's material cost is lower and the current price is comparable to that of PVB. (2) EvA is also simpler in processing the material.

対し、EVAは水洗工程を省略でき、調湿処理もPVB
はど厳しくない。That is, in order to prevent PVBViPVB from adhering itself, a heavy coating is usually applied to the surface and wound into a roll. Therefore, when used in the process of assembling solar cell panels, it is necessary to perform humidity conditioning treatment for about one day after washing with water. On the other hand, EVA can omit the water washing process, and PVB can also handle humidity control.
It's not harsh.

On the other hand, since PVB is laminated on a principle that does not use a crosslinking reaction, its softening property against temperature is reversible, and it softens at high temperatures.

二重真空方式を用いる必要がある。In addition, regarding the reliability test items of solar cell panels, please refer to J.
P L (Jet Propulsion Labo
The test items have been proposed by, for example, -40°C, and are being standardized in Japan.
Temperature/humidity cycle test in an atmosphere of ~80℃, RH (relative humidity) 90% or higher; High temperature/humidity test at 80℃, RH 90% or higher; Low temperature test at -40℃; -40℃~80℃ temperature shock test; salt water fog test force under 5% salt water; the purpose is to guarantee the lifespan of the solar panel, which is said to be about 20 years. In order to obtain highly reliable solar cell panels that pass these test items, lamination using EVA requires a single vacuum pumping method using a rubber bag, which is the usual method. It is necessary to use a double vacuum system as shown in Figure 3.

13 was evacuated, and the laminate (1, 41 was evacuated to ICVA (2
1) and (2) are heated in a molten state at a temperature range that does not cause a crosslinking reaction, for example, about 120°C. Next, while keeping the second chamber α2 in vacuum, the first chamber αυ is brought to atmospheric pressure. Then, the laminate Oa is compressed by atmospheric pressure in a vacuum through the diaphragm 0. Next, the EVA is heated to a temperature range where a crosslinking reaction occurs.This temperature is about 150°C. The temperature is maintained at this temperature until the crosslinking reaction is completed, and then, after cooling, the laminate α is taken out.
A solar cell, cell/ξ panel using the EVA filler (2) as shown in a part of the figure is formed, and the bonding process is completed.

Since the solar cells are pressurized in a molten state under vacuum, movement of the solar cells occurs. That is, even if the cells (3) are fixedly set in a desired position by soldering, after bonding, as shown in FIG.
) moves outward. In severe cases, some cells (3) may come out outside the glass plate (1). In order to prevent this outward movement, it is possible to tape the periphery of the laminate 0a, but in this case, the sixth
As shown in the figure, a phenomenon occurs in which the cells (3) in each column move to the center and the cells (3) come into contact with each other. If the cells (3) come into contact with each other, not only will there be problems in appearance, but also a short circuit phenomenon will occur in which the desired electromotive force cannot be obtained as a solar relay.

、ガラス板の外側へ出てしまうという現象である。Furthermore, in order to prevent contact between cells (3) due to movement, a seventh
As shown in the figure, on the back side of cell (3),
In addition to the ribbon lead (c) that electrically connects the cells, a rigid insulator bridge (a) is fixed to the cell (3) using adhesive to maintain a constant distance between adjacent cells in the horizontal direction. It is possible to do so. However, the process becomes complicated due to the large number of bridges (A) and the adhesion work, and even if contact between the cells (3) can be prevented, the entire IJ ring moves after the bonding process. There is a problem. That is, this is a phenomenon in which the cell (3) moves to the vicinity of the end face of the cover glass or comes out to the outside of the glass plate.
本発明は上述の問題点に鑑みなされたものであり充填材

The temperature is 30°C. When the temperature of the laminate Oa reaches 120° C., the first chamber (11) is returned to atmospheric pressure and the laminate Oa is pressure-bonded in a vacuum. Next, the temperature is increased until it reaches 150°C, and after reaching 150°C, it is held for 20 minutes, for example, in order to sufficiently carry out the crosslinking reaction. Then, after the temperature of the laminate is lowered to, for example, 50° C. or lower, the second chamber (I side) is returned to atmospheric pressure. In this case, the micro glass CF
G-24 and Crameglass 230 suppress the movement of the solar cell (3) and are also compatible with EVA, allowing the string to be bonded without causing bubble defects.
