•Monolayer graphene/Si Schottkey solar cell was fabricated.•Chemical doping can effectively tune the work function of graphene film.•Chemical doping has significant effect on the device performance.•The top-grid device structure with graphene is promising with low-cost and high efficiency.
Monolayer graphene/Si Schottkey solar cell was fabricated using a top-grid structure. In comparison with the prevailing “top-window” structure, the newly-designed device structure has simplified the fabrication procedures to avoid ultraviolet (UV) photolithography and SiO2-eching. We systematically investigated the effect of chemical doping as well as device area on the device performance. It was found that a power conversion efficiency (PCE) of 5.9% can be achieved by engineering the work function of graphene through chemical doping. Our study indicates that top grid structure is suitable to make low-cost, large area and high efficiency graphene/Si Schottkey solar cell.
