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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
