“…Among all experimented shape, we observed that sphere shape is the most optimized size of nanoparticle as shown in the figure. Beside the impact on absorption of light, sphere nanoparticles are capable of producing high, surface plasmons, polaritron, strong near field enhancement and larger scattering angle [8,9]. These are the most important parameters for enhanced current density.…”

“…On the basis of advancement in technology solar cells can be divided into three generations namely first generation, second generation and third generation. First generation solar cells are known for their high-cost and high efficiency [8]. But production of first generation solar cells is a laboured task which is one of the major factor that are responsible for its high cost.…”

In this study we present optimized shape, size and material of plasmonic nanoparticles in thin film solar cell. For this purpose, we chose silicon active layer solar cell, on the top of active layer another layer of silicon dioxide was used as antireflection coating. Thickness of ARC layer was kept 71nm. On the top of ARC layer metallic nanoparticles were placed. Parameters of NP’s such as shape, size and material were varied. Respective variations in the absorption of light in the active silicon layer were observed respectively. Absorption patterns were plotted against wavelength range of 400nm to 1400nm of incident light radiation using Finite Element Method (FEM). Results revealed the most optimized size and shape of nanoparticles that can contribute to the absorption of light in the active layer of the solar cell. Results also distinguished the best material for nanoparticle.

“…Recently light-trapping structures have been utilized in different ways to increase the absorption of plasmonic solar cells. Several structures including surface texturing [4][5][6], anti-reflection coatings [7,8], photonic crystals [9], nanogratings [10,11], and metallic nanoparticles [12][13] have been presented to enhance the absorption of plasmonic solar cells. Solar cells are generally classified into four generations [14][15][16][17][18].…”

In this paper, a plasmonic solar cell using silver nanoparticles is presented. The unit cell structure composes of two layers, each containing a silver nanoparticle deposited on the absorber layer and covered with an indium tin oxide layer. Nanoparticle structure has been used for light-trapping to increase the absorption of plasmonic solar cells. By various light trapping techniques, light can be concentrated in a thin absorber layer. As it will be clarified, through varying the geometry of these nanoparticle structures, the absorption peaks can be directed. All simulation data are obtained using the finite element method. The proposed model achieves two absorption peaks existing at 1.07 μm and 1.17 μm, each with absorptions of around 50%. The parameters of optimized performance have been specified. The results indicate that this model shows an absorption full width at half maximum, reaching 122 nm. Moreover, it can be noticed that the absorption peak can be increased to reach 0.5. The proposed structure has potential applications in the absorption of the infra-red part of the solar spectrum.

The photonic and plasmonic nanostructures are highly feasible for enhanced light trapping mechanisms. These nanostructures hold great promises for better photovoltaic performance by yielding the highest light-harvesting photons within the few nanometer absorber regions. The shed light on the nano-scaled structures (thin films and nanogratings) is responsible for the highest scattering mechanism with the omnidirectional diffraction angles and enhanced life time of the photons. In this research work, we have focused on improved ultrathin film amorphous silicon (a-Si) solar cell performance, which was integrated by top-SiO 2 and bottom-Ag nanogratings as a backside reflector by using rigorous coupled-wave analysis method. The SiO 2 antireflection coating, nanogratings, and absorber (a-Si) layer thicknesses were optimized for better photovoltaic performance. With the influence of optimization parameters, the highest current density of 27.03 and 33.53 mA/cm 2 were obtained from transverse electric and transverse magnetic polarization conditions due to the surface guided-mode, Fabry-Perot resonance, surface excitation, localized fields, and surface plasmon polariton modes.
