Sustainable plasmonic photocurrents are generated by gold and silver nanoparticles, located at a TiO2/hole conductor interface. The spectral photocurrent response closely follows the surface plasmon absorption bands of the metal particles. A simple nanoparticle self-assembly method for the solar cell fabrication is presented. Three mechanisms for plasmon-induced charge separation are proposed.
