Modulation of the photoelectrochemical behavior of Au nanocluster–TiO₂ electrode by doping

Abstract

by Ag doping and explain its influence on solar cell performance. Our in-depth spectroscopic and electrochemical characterization combined with computational study reveals that the performance-dictating factors respond in different manners to the Ag doping level, and we determine that the best compromise is the incorporation of a single Ag atom into an Au NC. This new insight highlights the unique aspect of NCs-susceptibility to atomic level doping-and helps establish a new design principle for efficient NC-based solar cells.
