Abstract

Oxide-metal-oxide structures are an alternative to single material transparent electrical contacts. Among other advantages, these multilayer systems provide good conductivity and transmittance, even when fabricated at room temperature. Low temperature processing is a requirement for silicon thin-film solar cells on various flexible substrates. The design and fabrication of oxide-metal-oxide structures based on ZnO:Al and Ag are investigated in this work. Further the integration of an optimized multilayer electrode into an amorphous silicon solar cell in substrate configuration was performed. Measurement results and possible loss mechanisms are discussed.
