“…An interesting route adopted to enhance the organic solar cells [145,146], dye-sensitized solar cells [147], and Si-based solar cells [148][149][150][151] conversion efficiency has proved to be the metal NPs' incorporation in the cell. In fact, the right engineering of metal NPs in the photovoltaic devices increases the cell short-circuit current density and fill factor (enhancing the cell conversion efficiency) [152][153][154].…”

Abstract:In this review, we discuss the basic concepts related to (co-)evaporation and (co)sputtering based fabrication methods and the electrical properties of polymer-metal nanocomposite films. Within the organic-inorganic hybrid nanocomposites research framework, the field related to metal-polymer nanocomposites is attracting much interest. In fact, it is opening pathways for engineering flexible composites that exhibit advantageous electrical, optical, or mechanical properties. The metal-polymer nanocomposites research field is, now, a wide, complex, and important part of the nanotechnology revolution. So, with this review we aim, starting from the discussion of specific cases, to focus our attention on the basic microscopic mechanisms and processes and the general concepts suitable for the interpretation of material properties and structure-property correlations. The review aims, in addition, to provide a comprehensive schematization of the main technological applications currently in development worldwide.

“…RI-matched conditions are widely modeled using effective media approximations, but such approximations are limited to real dielectrics with near-zero dispersion within the spectral region of interest. Instantiations like photovoltaics [63] often preclude implementation or modeling using RI-matching.…”

a b s t r a c tTwo-dimensional metamaterials support both plasmonic and coupled lattice (Fano) resonant modes that together could enhance optoelectronics. Descriptions for plasmon excitation in Fano resonant lattices in non-vacuum environments typically use idealized, homogeneous matrices due to computational expense and limitations of common approaches. This work described both localized and coupled resonance activity of twodimensional, square lattices of gold (Au) nanospheres (NS) in discontinuous, complex dielectric media using compact synthesis of discrete and coupled dipole approximations. This multi-scale approach supported attribution of experimentally observed spectral resonance energy and bandwidth to interactions between metal and dielectric substrate (s) supporting the lattices. Effective polarizabilities of single AuNS, either in vacuo or supported by glass and/or indium tin oxide (ITO) substrates, were obtained with discrete dipole approximation (DDA). This showed plasmon energy transport varied with type of substrate: glass increased scattering, while ITO increased absorption and energy confinement. Far-field lattice interactions between AuNS with/without substrates were computed by coupled dipole approximation (CDA) using effective polarizabilities. This showed glass enhanced diffractive features (e.g., coupled lattice resonance), while ITO supported plasmon modes. This compact, multiscale approach to describe metasurfaces in complex environments could accelerate their development and application.

“…A variety of nanostructure-based light trapping designs have thus been proposed. For example, several noble metal-based nanostructures were investigated at the front surface of the cells, utilizing the scattering effect induced by the surface plasmon excitation of the metal particles, which may effectively enhance the light absorption in the cells [8][9][10][11][12][13][14][15]. Besides, designs focusing on the increase of the light's optical path length were also reported, wherein the refraction of light into large angles allows the light to be reflected multiple times before escaping [16][17][18][19].…”

We report on an investigation into the light trapping efficiency for structures of thin film silicon solar cells, with silver nanoparticle arrays at both front and rear surfaces of the cells. The light trapping efficiencies of the structures are quantified by the weighted mean values of the photons absorbed by the silicon layer, over a wavelength range of 400 to 1100 nm. The weighted mean values are calculated under various combinations of the structural parameters for the silver nanoparticle arrays. The results show that efficient light trapping structures of the solar cells can be achieved by carefully choosing the structural parameters of the metal arrays. This great light absorption by the cell is attributed to the effects induced by the surface plasmon excitation of the metal particles. Based on the analyses, we also suggest that the method employed in this work may be a useful tool to probe other similar structures of the solar cells with metal nanoparticle arrays.
