Researchers at Japan's Hokkaido University report sandwiching a titanium dioxide film measuring 30 nanometers in thickness with a 100nm gold film and a layer of gold nanoparticles to create a photoelectrode device that boasts an energy-conversion efficiency of 85%. "Our photoelectrode successfully created a new condition in which plasmon and visible light trapped in the titanium oxide layer strongly interact, allowing light with a broad range of wavelengths to be absorbed by gold nanoparticles," says Hiroaki Misawa, lead author of the study.
