Ultrathin organic bulk heterojunction solar cells: Plasmon enhanced performance using Au nanoparticles

Fiberoptic nanobiosensor: A quantitative calibration method

“…Although the full set has not been analyzed, some preliminary results are clear. For 23nm AuNPs, the response peaks at about 20-25% coverage, similar to the findings in [18]. It is also clear that poor AuNP selfassembly can decrease sensor response by as much as 70%.…”

“…By measuring the response to protein binding at various AuNP coverages, it should be optimize sensor performance. Simulations on nanorod arrays indicate that response is a complex function of the AuNP fill-fraction coverage, and that there is an optimal coverage that maximized performance [18]. Furthermore, low quality monolayers ( Fig.…”

Nanostructures induced light harvesting enhancement in organic photovoltaics

“…Plasmonic nanostructures, such as periodic metal gratings [88][89][90], metal NPs [91][92][93][94], random corrugations [95][96][97] and biomimetic structures [98][99][100], have been investigated universally involving light concentration and manipulation in OPVs. Various kinds of plasmonic nanostructures can effectively trap light inside the photoactive layer owing to the excitation of the surface plasmonic effect, which is the collective oscillations of conductive electrons at the metal/dielectric interface.…”

Plasmonic excitation-assisted optical and electric enhancement in ultra-thin solar cells: the influence of nano-strip cross section

“…Noble metal core-shells nano-cubes and nano-sphere have also been of interest and showed to be influential in different devices including solar cells. [26][27][28][29][30][31][32] Both silver and aluminum nano-cubes demonstrated larger increase in the fraction of light coupled into the substrate compared to traditional silver nano-sphere. 33 Cole and Halas in their work 34 determined the ideal distribution of metallic nano-sphere and nano-shells.…”
