Directing the Absorption Peaks of Plasmoinc Solar Cell

Abstract

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.

A Novel SDM Discrete Search-Based Parameter Estimation for PV Solar Cells and Modules

“…In contrast, a current source is added under solar irradiance to represent the generated photo-electric current. Silver nanoparticles and indium oxide are deposited on the surface of the two layers of the semiconductor regions of the solar cell can increase the absorption of the light to increase the power conversion efficiency [24]. Two resistors are added; one is in series to define the metal electrode contact resistances, while the second represents the diode leakage current [25].…”
