“…The excited MNPs thereby strongly absorb (near-field effect) and scatter (far-field effect) the incident light, producing an enhancement up to a factor of 100 [3], in the electric field surrounding them [8]. Previous studies showed that the PCE of BHJOSCs was improved considerably by MNPs incorporated into OSC layers either on top of indium tin oxide (ITO) [9][10][11][12], within poly(3,4-ethyl-enedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) [13][14][15], within P3HT:PCBM [16], or with the back electrode [17].…”

Abstract:In this work, the effect of gold nanorods on the performance of poly(3-hexylthiophene-2,5-diyl):[6,6]-phenyl-C 61 -butyric-acid-methyl-ester bulk heterojunction solar cells was investigated. Gold nanorods were introduced into the anodic buffer layer by simply blending them with the solution of poly(3,4-ethyl-enedioxythiophene):poly(styrenesulfonate). Even with a fairly low density of the nanorods, the resulting devices showed a remarkable 21.3% enhancement in the power conversion efficiency and a 13% enlargement in the short circuit current. By examining the absorbance profiles of active films made with different conditions, such enhancements can be related to the localized transverse and longitudinal plasmon resonance modes in the metallic nanoparticles. Gold nanorods helped as well in reducing the device series resistance by up to 36%, which also contributed to the global enhancement in the efficiency.

“…This is in part because of the relatively narrow optical wavelength range in which typical donor and acceptor molecules absorb strongly. Seemingly the tunability of particle plasmon resonances via variation of their shapes, size, and dielectric environment should allow a broader spectral absorption range [4] for hybrid metallic nanostructure/OSC devices, which might be expected to produce enhanced solar cell efficiency [5][6][7][8][9][10], as has been found for Si-based devices [11]. Reports of the efficacy of this approach [5][6][7][8][9][10]12] however are contradictory.…”

Some, based upon simple transmission measurements and/or external quantum efficiency (EQE) measurements [5][6][7][8][9] of BHJ OSC devices which incorporated small (i.e., <50 nm in diameter) Ag or Au nanospheres, indicate an increase in the efficiency.…”

Effect of Extended Extinction from Gold Nanopillar Arrays on the Absorbance Spectrum of a Bulk Heterojunction Organic Solar Cell

et al. 2015

Abstract:We report on the effects of enhanced absorption/scattering from arrays of Au nanopillars of varied size and spacing on the spectral response of a P3HT:PCBM bulk heterojunction solar cell. Nanopillar array-patterned devices do show increased optical extinction within a narrow range of wavelengths compared to control samples without such arrays. The measured external quantum efficiency and calculated absorbance, however, both show a decrease near the corresponding wavelengths. Numerical simulations indicate that for relatively narrow nanopillars, the increased optical extinction is dominated by absorption within the nanopillars, rather than scattering, and is likely dissipated by Joule heating.

“…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.…”

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

2015

The effects of Ag nano-strips with triangle, rectangular and trapezoid cross sections on the optical absorption, generation rate, and short-circuit current density of ultra-thin solar cells were investigated. By putting the nano-strips as a grating structure on the top of the solar cells, the waveguide, surface plasmon polariton (SPP), and localized surface plasmon (LSP) modes, which are excited with the assistance of nano-strips, were evaluated in TE and TM polarizations. The results show, firstly, the TM modes are more influential than TE modes in optical and electrical properties enhancement of solar cell, because of plasmonic excitations in TM mode. Secondly, the trapezoid nano-strips reveal noticeable impact on the optical absorption, generation rate, and short-circuit current density enhancement than triangle and rectangular ones. In particular, the absorption of long wavelengths which is a challenge in ultra-thin solar cells is significantly improved by using Ag trapezoid nano-strips.
