Nanostructures for Enhanced Light Absorption in Solar Energy Devices

Figure 3

Elliptically-shaped silver nanoparticles show two separate plasmon resonance frequencies for light polarized parallel to the short and long axes, respectively. The graph demonstrates the effect of plasmon-mediated photodesorption of NO from Graphite surface (from [8]). The strong size dependent variation of the photoyield is in contrast with the smooth increase of the total Ag coverage (see dashed line).
