Geometrical Optimization of 2D MoS2-Ag Rectangular and Triangular Grating for Enhanced Solar Cell Efficiency

This study introduces a novel investigation into the use of MoS2-Ag rectangular and triangular grating structures to achieve this goal. Performing finite element analysis with the COMSOL 5.3a  RF module provides the possibility to explore the impact of various silver (Ag) grating configurations on the absorption of light in photovoltaic (PV) cells. In order to find the best combination of MoS2 thickness, slit width, and metallic grating while keeping the periodicity of the grating device unchanged, an optimum value is calculated. The zeroth-order transmission spectra and near-field plots of the Fano-resonance (dip) associated with the excitation of the SPPs are carefully analyzed. Our findings reveal that specific configuration of rectangular grating, MoS2 thickness of 50  nm, and a slit width approximately half or just over half of the periodicity significantly enhances the light absorption. This research not only demonstrates the critical role of grating geometry in improving solar cell efficiency but also lays the groundwork for future advancements in solar energ y technologies. By employing both far and near field analyses and rigorous statistical validation, our study offers a robust model for the geometrical optimization of grating structures, presenting a clear, impactful insight into the potential of these technologies for solar energy enhancement.
