Surface plasmon resonance of layer-by-layer gold nanoparticles induced photoelectric current in environmentally-friendly plasmon-sensitized solar cell

Abstract

Layer-by-layer gold nanoparticles are used to generate photocurrent in an environmentally-friendly plasmon-sensitized solar cell towing to surface plasmon resonance. The efficiency of the photoelectric conversion of gold nanoparticle layers is increased as the intensity of surface plasmon resonance increases. We also explain the experimental results by modeling the phenomenon of charge separation and photocurrent formation, and the relationship between surface plasmon resonance and photocurrent formation, which has potential application in plasmon-sensitized solar cells and plasmonic solar cells in the future.

Direct imaging of the near field and dynamics of surface plasmon resonance on gold nanostructures using photoemission electron microscopy

“…These unique properties promote the application of LSPR in many fields, such as surface-enhanced Raman scattering, [5][6][7][8] sensing, 1,9,10 plasmonassisted photochemical reactions 4,11,12 and photocurrent generation. [13][14][15] To further understand the LSPR mechanism and to optimize the design of the plasmonic nanostructures for most applications, the near-field properties of the LSPR fields (especially the near-field distribution of the plasmonic nanostructures) must be determined. To date, investigations of the optical properties of LSPR have largely relied on far-field spectroscopic techniques or numerical simulations.…”

Nanowire-supported plasmonic waveguide for remote excitation of surface-enhanced Raman scattering

“…The former could overcome the traditional diffraction limit in dielectric optics and be the key approach to overcoming the bottleneck of the miniaturization of nanophotonic devices and large-scale on-chip integrated circuits for next-generation information technology. [5][6][7][8][9][10][11] The extremely enhanced EM field caused by the latter has great application values in various fields, such as surface-enhanced spectrum, [12][13][14][15] surface plasmon resonance sensors, [16][17][18][19] ultra transmission, 20,21 plasmonic trapping, 22,23 plasmonic-enhanced emission, 24,25 quantum communication, 26,27 super-resolution microscopy, 28 cloaking, 29 photothermal cancer therapy, 30,31 steam generation, 30,32,33 holography, 34 photovoltaics [35][36][37] and water splitting. [38][39][40] One of the most promising applications of SPPs, especially localized SPPs, is surface-enhanced Raman scattering (SERS), which has been studied both theoretically and experimentally for many decades.…”

The operation mechanism of poly(9,9-dioctylfluorenyl-2,7-diyl) dots in high efficiency polymer solar cells

“…4 But it still lags behind the commercial application level and there are many challenges to overcome on the way to competitively efficient devices, including the need for a detailed knowledge of charge transport and spectrum utilization. Much effort have been made in recent years to pursue polymer solar cells exhibiting high PCE, such as designing low-bandgap organic semiconductor, [5][6][7] developing novel device structure, [8][9][10] and optimizing the film morphology. [11][12][13] Although the perceived advantages of polymer solar cells are attractive, the efficiency of polymer solar cells (PSCs) is still limited by efficient hopping charge transport, and charge transport is further hindered by the presence of structural traps in the form of incomplete pathways in the percolation network.…”
