Solar battery and process for preparing same.

摘要

A solar battery comprises a substrate, a first semiconductor layer of a first conduction type comprising a single crystal singly grown on a nucleation surface (SNDL) formed on the surface of said substrate as the base for growing, said nucleation surface (SNDL) being comprised of a material which is sufficiently greater in nucleation density (ND) than the material constituting the surface of said substrate and having a sufficiently fine area such that only a single nucleus grows, a second semiconductor layer of a second conduction type different than the conduction type of said first semiconductor layer and means for taking out the power.
