Abstract
In this study, we introduce an innovative silicon solar cell design aimed at enhancing both current density and overall
efficiency. This novel architecture features a unique combination of alternating or window-shaped doping profiles at the top
layer, complemented by a graphene grating layer situated in the middle, and strategically positioned gold nanoparticles
between the doping and grating layers. We conducted a comprehensive performance evaluation of various solar cell
configurations, including a basic silicon solar cell, cells with window doping, grating, nanoparticles, and a combination of
doping, nanoparticles, and grating. Our findings reveal that the proposed structure, with its synergistic integration of grating,
window-shaped doping, and nanoparticles, significantly amplifies the electric field strength within the active region. This
enhancement leads to a remarkable improvement in solar cell performance, highlighted by a quantum efficiency value
reaching up to 81%, a short-circuit current density of 35 mA/cm^2, a fill factor (FF) of 83%, and an open-circuit voltage
(VOC) of 0.66 V. These results underscore the potential of the proposed design in pushing the boundaries of silicon solar
cell efficiency and performance.
