“…Consequently, under the presence of Au NDs, any enhancement in device performance could not be obtained. Compared to previous reports, size and density of Au NDs were not so different . Size ranges of metal nanostructures synthesized by chemical technology in previous reports were from several nanometers to several tens of nanometers.…”

Size, shape, and density‐controlled metal nanostructure, Au nanodot lattices fabricated by electron beam lithography, were embedded in thin organic solar cell consisting of PC71BM:PCPDTBT. The effects of their size and density on device performance were examined. Even though dipole res‐onances of Au nanodots were consistent with the absorption range of the active materials, there were no improvements in device performance under any sizes and densities. In addition, under high volume density of Au nanodots to PEDOT:PSS layer, the device performance was deteriorated. These results indicated that not only size and density but also other factors which determine light scattering characteristics greatly affect the device performance of solar cells.

“…89 Using mNPs which are smaller than the wavelength of light entering a device, can increase the amount of light absorbed by the solar cell. 90,91 Similar to TMOs, mNPs can be formed through a variety of methods including chemical synthesis, 92 thermal annealing, 93 E-beam lithography, 90 and laser annealing. 94 Solution-processed mNPs have the same dispersion and lm quality limitations as observed for similarly prepared TMOs, while the thermal methodology used requires high temperatures and vacuum processing which adds costs and complexity.…”

Recent developments in solution processable single junction polymer solar cells have led to a significant improvement in power conversion efficiencies from ∼5% to beyond 9%. While much of the initial efficiency improvements were driven through judicious design of donor polymers, it is the engineering of device architectures through the incorporation of inorganic nanostructures and better processing that has continued the efficiency gains. Inorganic nano-components such as carbon nanotubes, graphene and its derivatives, metal nanoparticles and metal oxides have played a central role in improving device performance and longevity beyond those achieved by conventional 3G polymer solar cells. The present work aims to summarise the diverse roles played by the nanosystems and features in state of the art next generation (4G) polymer solar cells. The challenges associated with the engineering of such devices for future deployment are also discussed.

“…Plasmonic nanoparticles have become an increasingly common research area as well as becoming a key component in many important applications, such as solar energy harvesting [1][2][3][4][5][6], chemical sensing via surface-enhanced spectroscopies [7,[8][9][10][11][12][13][14], cancer treatment [15,16] and optical encoding of information [17][18][19][20] to name a few. The main reason behind their adaptability, to these and other prominent applications, is their unique optical properties that allow for the manipulation of light below the diffraction limit.…”

Nanoconstruction of metals is a significant challenge for the future manufacturing of plasmonic devices. Such a technology requires the development of ultra-fast, high-throughput and low cost fabrication schemes. Laser processing can be considered as such and can potentially represent an unrivalled tool towards the anticipated arrival of modules based in metallic nanostructures, with an extra advantage: the ease of scalability. Specifically, laser nanostructuring of either thin metal films or ceramic/metal multilayers and composites can result on surface or subsurface plasmonic patterns, respectively, with many potential applications. In this chapter, the photo-thermal processes involved in surface and subsurface nanostructuring are discussed and processes to develop functional plasmonic nanostructures with pre-determined morphology are demonstrated. For the subsurface plasmonic conformations, the temperature gradients that are developed spatially across the metal/dielectric structure during the laser processing can be utilized. For the surface plasmonic nanoassembling, the ability to tune the laser's wavelength to either match the absorption spectral profile of the metal or to be resonant with the plasma oscillation frequency can be utilised, i.e. different optical absorption mechanisms that are size-selective can be probed. Both processes can serve as a platform for stimulating further progress towards the engineering of large-scale plasmonic devices.
