Solar Cells: A Solid-State Plasmonic Solar Cell via Metal Nanoparticle Self-Assembly (Adv. Mater. 35/2012)



original image

Incident light excites surface plasmon resonances in metal nanoparticles. Located at a TiO2/hole conductor interface, gold and silver nanoparticles induce sustainable photocurrents upon excitation. The image (by Inga Tegtmeier) depicts the excitation of silver nanoparticles with turquoise light and the electrons transferred to the transparent electrode. A simple fabrication method for this plasmonic solar cell, based on metal nanoparticle self-assembly, is described by U. Bach and co-workers on page 4750.
