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 SiO 2 and an inorganic layer having a lower density than SiO 2 , and the film having a lower density than SiO 2 is directly formed on the substrate and the second electrode.

First claim

The invention claimed is:

1. A solar battery comprising:
a substrate;
a first electrode formed on the substrate;
a power generating element formed so as to be connected with the first electrode;
a second electrode formed so as to be connected with the power generating element;
an inorganic barrier layer including portions at least in contact with the substrate and the second electrode;
a first extraction terminal connected to the first electrode;
a second extraction te…
