“…Therefore, due to this the EF no longer remains uniform around the surface of nanoparticle and hence, the conduction electrons start to oscillate out of phase with each other which results in reduced scattering. 42 Hence, in further study the radius of the individual interacting particles is taken to be 50 nm. …”

The plasmonic coupling between the interacting noble metal nanoparticles plays an important role to influence the optical properties of arrays. In this work, we have extended the Mie theory results of our recent communication to include the effect of particle interactions between the alloy nanoparticles by varying interparticle distance and number of particles. The localized surface plasmon resonance (LSPR) peak position, full width at half maxima (FWHM) and scattering efficiency of one dimensional (1D) bimetallic alloy nanosphere (BANS) arrays of earlier optimized compositions i.e. Ag0.75Au0.25, Au0.25Cu0.75 and Ag0.50Cu0.50 have been studied presently by using discrete dipole approximation (DDA) simulations. Studies have been made to optimize size of the nanosphere, number of spheres in the arrays, material and the interparticle distance. It has been found that both the scattering efficiency and FWHM (bandwidth) can be controlled in the large region of the electromagnetic (EM) spectrum by varying the number of interacting particles and interparticle distance. In comparison to other alloy arrays, Ag0.50Cu0.50 BANS arrays (each of particle radius 50 nm) shows larger tunability of LSPR with wide bandwidth (essential condition for plasmonic solar cells).

“…Surface plasmon is the collective oscillations of excited free electrons of metallic particles. This unique property of metallic nanoparticles (NPs) can be used to enhance the optical absorption of solar cells through scattering of light and near-field concentration of light [11][12][13][14][15][16][17]. The contribution of these mechanisms depends on the nanoparticle material, shape, and size, and the refractive index of the surrounding dielectric.…”

In this article, the effect of plasmonic properties of metal nanoparticles with different shapes, and moreover, their plasmonic-photonic interaction, on solar cell performance were investigated and simulated. Because of low conversion efficiency and then high cost of solar cells, it is difficult to commercialize and replace them with conventional energy resources. But in recent years, the plasmonic solar cell has been very popular. In this study, it is shown that the enhancement of near-field electromagnetic waves severely affects the generation rate, which handles the carrier's generation in the solar cell equations and causes alteration of the photocurrent. This means that by manipulating the plasmonic properties of nanoparticles (shape and density) and their interaction with photons in solar cell structure, distribution of electromagnetic fields will be altered. Hence, the optical power related to the poynting vector is changed. So, with the aim of improving the solar cell some important parameters such as alteration of nanoparticle shape and their interdistance were investigated. Finally, a comparison between traditional solar cells and our improved structure was undertaken.

The influence of parameters of an aluminum nanoparticle layer on the characteristics of a thin-film amorphous silicon solar cell has been studied using the computer simulation methods. A design with a regular arrangement of nanoparticles both on the front and back sides of the solar cell has been considered. The distribution of photogeneration rate in the amorphous silicon layer has been obtained for different values of the nanoparticle radius. The effects of nanoparticle radius and nanoparticle spacing on the electrical characteristics of a solar cell have been analyzed. It has been shown that, with optimal parameters of nanoparticles, it is possible to significantly increase the efficiency of solar cells.
