Abstract

This paper reports the use of Au nanoparticles (NPs) as electron transfer bridge layers to improve the photocurrent of viologen/Ru complex-based photoelectrochemical cells. The Ru complex/ viologen/Au NPs on electrodes were prepared using self-assembled monolayers. The cell system showed an excellent photocurrent of 25 nA/cm ² under the 1.5 air mass condition (/ = 100 mW/cm ²), which is five times greater than Au NPs due to the reduced recombination reaction.
