  • Publication number: 20130098429
    Abstract: Disclosed is a solar cell module which uses polyvinyl chloride as the backing and does not undergo a decrease in adhesive strength between the backing and a sealing layer even when exposed to an outdoor environment. The solar cell module has a polyvinyl chloride backing, and a encapsulant-covered photoelectric conversion component and a weather-resistant layer that are laminated in this order on the backing. The module includes a first adhesive layer between the polyvinyl chloride backing and the encapsulant-covered photoelectric conversion component. The first adhesive layer is formed of a single layer, and contains a plurality of resins.
