Abstract

See full text

A thin epitaxial silicon solar cell includes one or more layers of doped oxides on the backside. A silicon nitride layer that serves as a moisture barrier is formed on the one or more layers of doped oxides. The doped oxides provide dopants for forming doped regions in an epitaxial silicon layer. Metal contacts are electrically coupled to the doped regions through the silicon nitride layer and the one or more layers of doped oxides.
