- Abstract
In this paper, we study the power absorbance enhancement in thin film silicon solar cells with the help of plasmonic sphere-cube hetero-dimer structures. Ag sphere-cube hetero-dimer structures are integrated on top of thin film crystalline silicon solar cells. The heterodimer structure highly localizes the light and redirects it inside the solar cell. Engineering the geometrical parameters and the gap between the sphere and the cube is a key parameter that determines the power absorbance enhancement in the solar cell. The simulation results show a broadband power absorbance enhancement compared to the plain cell and enhanced the photogenerated current. We compare different structures and materials of plasmonic nano single particle systems, symmetric sphere-sphere and cube-cube dimers, and sphere-cube hetero-dimers. The plasmonic sphere-cube heterodimer structure enhanced the absorbance of the solar cell compared to a plain cell.
