The present work reports a simple and direct sputtering deposition to form
solid state TiO 2 |Ag independent plasmonic solar cells. The independent
plasmonic solar cells are based on a Schottky barrier between two materials,
TiO 2 and Ag. The Ag functions as the absorber generating “hot” electrons, as
well as the contact for the solar cell. The Ag sputtering is performed for different
durations, to form Ag nanoparticles with a wide size distribution on the
surface of rough spray pyrolysis deposited TiO 2 .
