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.
