Abstract: Enhanced conversion efficiency with reduced cost of thin film solar cell is the primary objective of the scientific community. Light trapping mechanism is essential which have been explored and improved the performance of the solar cell. Past few decades, the plasmonic solar cell has been investigated in which actively involves metal nanostructure like nanoparticle or grating. Our numerical work analyzes the light absorption enhancement in the 1µm thin c-Si solar cell with different nanostructures. The optimal design combines front dielectric (ITO) and back metal (Ag) gratings as the reflector. This designed cell shows enhanced absorption through localized surface plasmon (LSP) or surface plasmon resonance (SPR). Comparing reference, the dual grating solar cell provides a significant efficiency from ~11% to 18.82%, which is a 71% enhancement. This enhancement has been attributed to the field localization and resonantly field scattering at the interface of the metal and active region.
