Enhancement of Dye Sensitized Solar Cell by Adsorption of Graphene Quantum Dots

NY. Muhammad, MN. Mohtar, MM. Ramli, S. Shafie, S. Shaban, and Y. Yusof
Abstract—Dye-sensitized solar cell (DSSC) is the third generation of solar cells that promises a simple procedure and relatively low-cost materials which can provide electricity by converting light energy into electrical energy. DSSC is a sandwich-like structure consists of conducting electrodes, sensitizer, and electrolyte. In this research, Graphene Quantum Dots (GQDs) is used as an enhancer for DSSC and it will be compared with the conventional DSSC performance. The time adsorption of GQDs is varied to study the improvement in the efficiency of DSSC. GQDs can increase the electron mobility hence increases the efficiency of DSSC. The presence of GQDs and the efficiency of DSSC are examined by using Energy-dispersive X-ray Spectroscopy (EDX) and solar simulator respectively. The result shows that the presence of GQDs have improved the efficiency of DSSC. As time adsorption of GQDs in DSSC increases, the efficiency of DSSC also increases.

Index Terms—Dye sensitized solar cell, Graphene Quantum Dots, power conversion efficiency, time adsorption.
