“…A longitudinal field is a localized Coulomb field, with no associated Poynting vector, that transmits electrostatic energy to the medium by means of scalar photons created by the scattered electric potential operator (0s), which is described by quantum electrodynamics [52][53][54][55]. As such, a semi-classical formalism in the Coulomb gauge [12] determines that the amount of absorption enhancement produced in a medium due to the longitudinal light scattered by an MNP, in the electrostatic regime, is given by the quantity I0s/0o| 2 , where 4>o is the incident potential.…”

A colloidal deposition technique is presented to construct long-range ordered hybrid arrays of self-assembled quantum dots and metal nanoparticles. Quantum dots are promising for novel opto-electronic devices but, in most cases, their optical transitions of interest lack sufficient light absorption to provide a significant impact in their implementation. A potential solution is to couple the dots with localized plasmons in metal nanoparticles. The extreme confinement of light in the near-field produced by the nanoparticles can potentially boost the absorption in the quantum dots by up to two orders of magnitude.In this work, light extinction measurements are employed to probe the plasmon resonance of spherical gold nanoparticles in lead sulfide colloidal quantum dots and amorphous silicon thin-films. Mie theory computations are used to analyze the experimental results and determine the absorption enhancement that can be generated by the highly intense near-field produced in the vicinity of the gold nanoparticles at their surface plasmon resonance.The results presented here are of interest for the development of plasmon-enhanced colloidal nanostructured photovoltaic materials, such as colloidal quantum dot intermediate-band solar cells.

“…A photonic crystal can be used either as an omnidirectional lossless reflector 4 or a diffractive element outside the photoactive layer 5,9 , or as a photoactive absorber [10][11][12][13][14][15][16][17] to couple incident light into quasi-guided modes. Plasmonic nanostructures enhance light absorption because they can scatter incident light into wave-guided modes 18 or surface plasmon-polariton modes 19,20 , or increase the optical electric field around nanostructures 21 .…”

Broadband light management using low-Q whispering gallery modes in spherical nanoshells

et al. 2012

Light trapping across a wide band of frequencies is important for applications such as solar cells and photodetectors. Here, we demonstrate a new approach to light management by forming whispering-gallery resonant modes inside a spherical nanoshell structure. The geometry of the structure gives rise to a low quality-factor, facilitating the coupling of light into the resonant modes and substantial enhancement of the light path in the active material, thus dramatically improving absorption. using nanocrystalline silicon (nc-si) as a model system, we observe broadband absorption enhancement across a large range of incident angles. The absorption of a single layer of 50-nm-thick spherical nanoshells is equivalent to a 1-µm-thick planar nc-si film. This light-trapping structure could enable the manufacturing of high-throughput ultra-thin film absorbers in a variety of material systems that demand shorter deposition time, less material usage and transferability to flexible substrates.

“…This type of deposition has been used on crystalline Si (c-Si), a-Si:H, and an InP/InGaAsP quantum well p-i-n structure [51,60,61]. Other deposition techniques include island formation on TCO's for organic photovoltaics, incorporation of metal nanoparticles inside the active layer, electron beam lithography, and electrodeposition [62,63,64,65,66].…”
