ル（ＰＶＢ）についての検討が幅広く行なわれている。As a method for sealing solar cells, a method of laminating transparent thermoplastic resin sheets using a roll or the like is attracting attention. Among such resin sheets, polyvinyl butyral (PVB), which is used as an interlayer film for laminated glass for automobiles, has been widely studied.

It cannot be used unless humidity is controlled, and general-purpose plastics such as polyethylene (PE) and polyvinyl chloride (
PVO), ethylene-vinyl acetate copolymer (EVA), etc. have disadvantages such as being expensive. Therefore, PvB
These EVA, PE, soft PVO as alternative materials
Transparent sheet materials such as
~100°C) has a drawback of poor adhesion to the surface material of the colon battery module such as glass. In order to improve this adhesion, for example, fjiVA has been devised to increase the vinyl acetate content, but these materials also contain some type of self-fusing inhibitor (for example, carnauba wax, etc.) to achieve self-fusing properties. ) has to be used, and furthermore, there are disadvantages such as a decrease in heat resistance. On the other hand, it is conceivable to use a sheet material such as ionomer resin that exhibits good pressure bonding properties at medium temperatures, but it is expensive.

上させることができる。On the other hand, the present inventor placed a solar cell module material composed of a surface material such as glass / a transparent thermoplastic resin sheet / a solar cell / a thermoplastic resin sheet / a back material under reduced pressure, and After removing gases such as air,
We proposed a method and device for modularizing solar cells, which consists of integrating the thermoplastic resin sheets by applying pressure using an elastic pressure film at a temperature above the melting point, and filed a patent application for the same. Such a method and apparatus offers many advantages and can greatly improve the performance of production solar modules compared to roll lamination methods as described above.
しかし、ＰＥなどは、一般に高温（２００℃以上）でな
いと良好な熱融性を示さないので、上記のモジュール化
法には首尾よく用いることができない。However, PE and the like generally do not exhibit good thermal meltability unless the temperature is high (200° C. or higher), so they cannot be successfully used in the above modularization method.

A module material was constructed by stacking VA-1/Tetra film in this order. The EVA-11 sheet was placed such that a layer of EVA with a vinyl acetate content of 33 inches was in contact with each of the glass and film. This module material was crimped and made into a module in the same manner as in Example 1. However, the mold temperature was 130°C. The product module was tested in the same manner as in Example 1, and the weather resistance and heat cycle resistance were good. Note that ETA-■ can be used directly without using wax or the like because the BVA layer with a vinyl acetate content of 14% acts as a self-fusing inhibitor. ETA7-) with a content of 30% requires the use of a self-fusing inhibitor such as wax).
