Abstract
A solar battery module has a structure in which a solar battery cell formed by a transparent electrode, a power generating element, and a back electrode is formed on a substrate, and it is sealed with a resin material such as EVA. However, there has been a problem that water enters from a gap between the substrate and a resin sealing material, thereby resulting in the corrosion of the resin or the solar battery cell. A barrier layer made of inorganic substances having portions in contact with the substrate and the second electrode is provided. Here, the barrier layer is formed by laminating at least SiOand an inorganic layer having a lower density than SiO, and the film having a lower density than SiOis directly formed on the substrate and the second electrode.
