Abstract

Nowadays, fossil fuel supply is decreasing over time. Thus, people are required to look for alternative energy sources that are renewable and environmentally friendly. Dye-Sensitized Solar Cells (DSSC) is one of the promising sources to overcome those problems. In this research, a DSSC with naphthol blue-black (NBB) as dye sensitizer has been developed. In order to improve the performance of the DSSC, NBB was modified by inserting Fe to form Fe-NBB complex compound. Fe-NBB showed light harvesting characteristic through MLCT phenomenon (Metal to Ligand Charge Transfer) at 273 nm and metal-ligand bonding at 486.06 cm-1 and 316.33 cm-1. NBB and its derivatives (Fe-NBB) were applied as dye sensitizer in the DSSC. The obtained open circuit voltage, short circuit current, and efficiency for NBB were 0.218 V, 0.096 mA/cm2 and 0.0083 %, respectively. While, Fe-NBB were 0.363 V, 0.567 mA/cm2 and 0.0925%.
