耐候性が十分でなかった。2. Description of the Related Art Conventionally, solar cells have been widely used for many general-purpose electric devices such as calculators and watches and outdoor electric devices where it is difficult to obtain a power source. It is protected by plastic and commercialized. The space between the cell and the protective cover is filled with space or a resin such as ethylene-vinyl acetate, polyvinyl alcohol, etc.

に提供するものである。Thus, the present invention has been completed based on the above findings, and the space between the cell and the protective cover is filled with an amorphous fluororesin having a fluorinated alicyclic structure in its main chain. The present invention newly provides a solar cell module characterized by:
【０００７】本発明で用いられる、主鎖に含フッ素脂肪
族環構造を有する非晶質フッ素樹脂は、吸湿性が低いた

上させることが可能である。Since the amorphous fluororesin having a fluorine-containing alicyclic structure in the main chain used in the present invention has low hygroscopicity, it is necessary to protect solar cells from moisture in the surroundings and improve moisture resistance. Is possible.
【０００８】また、該フッ素樹脂は紫外線の吸収がほと
んど無く耐候性が良好なために長期にわたる屋外での使
用に際しても透明性をそこなうことがない。Further, since the fluororesin hardly absorbs ultraviolet rays and has good weather resistance, it does not lose its transparency even when it is used outdoors for a long period of time.
【０００９】また、該フッ素樹脂は保護カバーとセルの

樹脂が好ましい。The fluororesin can also function as an adhesive between the protective cover and the cell. In that case, it is preferable to select a fluororesin having good adhesion to the protective cover and the cell. For example, a fluororesin having an adhesive group such as an alkoxysilyl group, a carboxylic acid group, a carboxylic acid ester group, a sulfonic acid group or a sulfonic acid ester group is preferable.

Fluorine resins such as ethylene-tetrafluoroethylene resin, perfluoro (ethylene propylene) resin, perfluoroalkoxy resin, polyvinylidene fluoride resin and polychlorotrifluoroethylene resin may be used.
【００１１】本発明のフッ素樹脂は、汎用樹脂に比べて
屈折率が低く、セル上に反射防止コートが施されていた
場合、その効果をそこなうことが少ない。The fluororesin of the present invention has a lower refractive index than a general-purpose resin, and when the antireflection coating is applied on the cell, the effect is less likely to be impaired.

知られているが、これらのフッ素樹脂の多くは結晶性を
有するため、光の散乱が起こり、透明性が良好でない。Usually, as the fluororesin, there are polytetrafluoroethylene resin, perfluoro (ethylenepropylene) resin, perfluoroalkoxy resin, polyvinylidene fluoride resin, ethylene-tetrafluoroethylene resin, polychlorotrifluoroethylene resin and the like. Although widely known, many of these fluororesins have crystallinity, so that light scattering occurs and the transparency is not good.

といった点から好適である。The non-crystalline fluorine-containing resin has excellent transparency because it does not scatter light due to crystals. As the non-crystalline fluorine-containing resin, tetrafluoroethylene, vinylidene fluoride and hexafluoropropylene are 37 to 48% by weight, 15 to 35% by weight and 26 to 4% by weight, respectively.
Examples include fluoroolefin-based copolymers such as 4% by weight of terpolymers and polymers having a fluorinated alicyclic structure. In particular, using a fluororesin having a fluorinated alicyclic structure in the main chain provides high efficiency because it has sufficient transparency, and because it is soluble in a solvent, it creates a void between the cell and the cover by coating. It is preferable because it can be filled.
