Enhancing solar cells with nanoparticles
Date:12/23/2008

he particles allows researchers to improve light capture at otherwise poorly-performing colors.

In their work, carried out at the FOM Institute for Atomic and Molecular Physics in The Netherlands, Catchpole and Polman showed that light capture for long-wavelength (reddish) light could be improved by a factor of more than ten. Previously Catchpole and co-workers at the University of New South Wales showed that overall light-gathering efficiency for solar cells using metallic nanoparticles can be improved by 30 percent.

"I think we are about three years from seeing plasmons in photovoltaic generation," says Catchpole, who has now started a new group studying surface plasmons at the Australian National University. "An important point about plasmonic solar cells is that they are applicable to any kind of solar cell." This includes the standard silicon or newer thin-film types.
