Modification of Methyl Orange dye as a light harvester on solar cell

Abstract

The purpose of this research is to modify methyl orange be a complex compound Fe (II) -methyl orange and apply it as a light harvester on DSSC (Dye-Sensitized Solar Cell) technology. Titanium dioxide was used as a semiconductor and synthesized from tetrabuthylorthotitanate (TBOT). The wavelength spectra of Fe (II)-methyl orange was characterized by UV-Vis spectrophotometer and showed d-d transition at 420.50 nm and charge transfer at 262 nm. The interaction of metal-ligand bonding (Fe-N) was characterized by FTIR spectrophotometer and shown at wavenumber 316.33 cm-1. Fe(II)-methyl orange was a paramagnetic compound with magnetic moment 3.9 BM and ionic compound because of its conductivity higher than its solvent. The photovoltaic analysis confirmed that Fe(II)-methyl orange produced a current of 40 mA, a voltage of 0.38 V and an efficiency of 0.24%.
