<P>PROBLEM TO BE SOLVED: To provide a solar cell device having a substrate protected against warpage. <P>SOLUTION: This solar cell device is equipped with a certain conductivity- type crystalline semiconductor substrate; an impurity layer which is formed on the inner light receiving surface side of the substrate, and of a conductivity- type opposite to that of the substrate; another impurity layer which is formed on the inner rear side of the substrate of the same conductivity-type with the substrate, and doped with impurities with high concentration; and light transmitting conductive films each formed on the impurity layers, so that the substrate can be prevented from being warped. <P>COPYRIGHT: (C)2003,JPO |
