(JP9064392-A)      The solar cell module includes a photovoltaic element (104) with a photoactive semiconductor layer as a photoelectric conversion member. The photovoltaic element is enclosed by a surface side covering material. The material covers a light receiving side face side of the element. A back part covers the rear face of the element.    The back covering material is a foamed material (102a). The material includes a member selected from a stacked body and a fibre, or a fibre in the foamed material. The fibre may be a woven or non-woven fabric. The back covering material has a smooth face.    ADVANTAGE -   Reduced size due to use of vacuum compression. Stable and safe to use in any environment. Flexible due to use of foamed material. Reliable. Good cushioning. Light.
