“…Both methods have been widely used to simulate the optical properties of artificial subwavelength nanostructures and are in good agreement with the experiment [42][43][44]. In addition to the bionic moth eye structure, researchers have designed a series of artificial nanostructures with good antireflection effects, including nanowires [45,46], nanocones [47,48], nanoholes [49,50], nanopyramids [51,52], and some complex composite structures [53,54]. Micronanomanufacturing technology is the key to realizing that artificial antireflection nanostructures can be applied to silicon solar cells.…”

Due to the ongoing depletion of fossil energy, alternative energy-sources and their respective conversion technologies have become very essential. An inexhaustible and clean energy form, which is already widely used, is solar energy. However, despite much progress in recent decades, due to the limitations of materials and manufacturing technology, the ability of solar cells to convert light into electrical energy is still not very high. Enhancing light absorption and reducing electric loss are the keys to improving the overall conversion efficiency of solar cells and reducing raw material costs. The former can be achieved by using micro/nanostructures and other surface features, while the latter can be realized by surface passivation. Researchers have developed different silicon-surface texturing methods to fabricate random or periodic micro/nanostructures on the surface of silicon wafers. Thanks to the special and efficient light-trapping effects of silicon micro/nanostructures, both full angle and wideband light absorption can be achieved. Different passivation methods and materials have also been widely studied, which helps to improve the surface recombination of photogenerated carriers caused by light trapping structure and significantly enhance the power conversion efficiency of Si solar cells. In this work, theoretical studies of enhanced light-trapping in micro/nanostructures are introduced. In addition, several advanced methods for preparing micro/nanostructures on the surface of monocrystalline silicon are discussed. These can be classified as top-down and bottom-up approaches. Furthermore, passivation methods for micro/nanostructures on the surface of monocrystalline silicon solar cells are reviewed, including chemical passivation and field-effect passivation. Finally, advantages and disadvantages of the micro/nanostructure preparation technologies, and light-trapping effects of the micro/nanostructures, which were fabricated using these manufacturing technologies were summarized. Moreover, the effects of different passivation technologies on the optical properties and electrical properties of these micro/nanostructures are studied. An outlook of expected and emerging research directions for monocrystalline silicon solar cells concludes this study.

In this paper, a randomly distributed plasmonic aluminum nanoparticle array is introduced on the top surface of conventional GaAs thin-film solar cells to improve sunlight harvesting. The performance of such photovoltaic structures is determined through monitoring the modification of its absorbance due to changing its structural parameters. A single Al nanoparticle array is integrated over the antireflective layer to boost the absorption spectra in both visible and near-infra-red regimes. Furthermore, the planar density of the plasmonic layer is presented as a crucial parameter in studying and investigating the performance of the solar cells. Then, we have introduced a double Al nanoparticle array as an imperfection from the regular uniform single array as it has different size particles and various spatial distributions. The comparison of performances was established using the enhancement percentage in the absorption. The findings illustrate that the structural parameters of the reported solar cell, especially the planar density of the plasmonic layer, have significant impacts on tuning solar energy harvesting. Additionally, increasing the plasmonic planar density enhances the absorption in the visible region. On the other hand, the absorption in the near-infrared regime becomes worse, and vice versa.

“…The motivating optical properties are determined by the localized and propagating surface Plasmon resonances (SPR). These Plasmonic resonances of the metal surfaces can be adapted by proper tuning of the physical and geometrical parameters of such structures [11,12].Because of these benefits the surface Plasmon resonance-based optical fiber sensors have drawn a lot of attention [13][14][15][16][17][18].For LSPR sensor various type of metals like silver, copper and aluminium used at the surface near sensing layer to excite these waves. Pradeep Kumar Teotia et al [19] obtained high sensitivity using multilayer grating configuration.…”

This paper present an investigation on Localized Surface Plasmon based optical fiber sensor and comparative performance of design with nanoparticles of different material on the tip of fiber. It is found that the Silver nanoparticles have higher sensitivity of 300nm/RIU and 10.7 figure of merit when refractive index of surrounding varies from 1.33 to 1.36. Whereas the copper and aluminum has the sensitivity of 133nm, 333nm, figure of merit of 2.7 and 8.1 respectively. It is also observed that the Surface Plasmon Resonance curve of silver nanoparticles has narrow width which improves the detection of accuracy as compared to copper and aluminum.
