Abstract

A thin-film photovoltaic device includes a semi-transparent back contact layer. The semi-transparent back contact layer includes a semi-transparent contact layer and a semi-transparent contact interface layer. The thin-film photovoltaic device may be formed in a substrate or superstrate configuration. A tandem thin-film photovoltaic device includes a semi-transparent interconnect layer. The semi-transparent interconnect layer includes a semi-transparent contact layer and a semi-transparent contact interface layer.
