Abstract

A significant Au particle size-dependent electrocatalytic effect has been shown in a sandwich type photoelectrochemical solar cell consisting of CdSquantum dot (QD)-sensitized TiO₂ photoelectrodes, Au nanoparticle (NP)-loaded SnO₂ counter electrodes, and a polysulfide electrolyte solution intervening between the electrodes.
