OPTIMIZATION OF ORGANIC DYE (5MSA) ON THE EFFICIENCY OF DYE-SENSITIZED SOLAR CELLS (DSSC)

The impartial of this study is to investigate the absorbance and electrochemical properties of organic dye 5-Methyl salicylaldehyde- Aniline (5MSA).To the best of our knowledge we have the first time produced the biodegradable organic dyes with a new band gap of small molecule 5MSA by slow evaporation method. The absorbance and electrochemical properties were tested by Ultraviolet-visible (UV-Vis),Fourier transform infrared (FTIR)spectroscopy, Photoluminescence and cyclic voltammetry (CV). The composition, particle size and structure of this dye were characterized by FESEM and XRD analysis. The results shows that the absorbance spectrum of dyes was at a wavelength from 200-500 nm. The dye also have C=N,C-N and O-H which important for anchoring in semiconductors. Moreover, the level energy of highest occupied molecular orbital and that of lowest unoccupied molecular orbital from organic dye 5-Methylsalicylaldehyde-aniline were -5.142eV and -3.572eV respectively. The findings show that the organic dye 5-Methylsalicylaldehyde-aniline dye may be a promising properties for DSSC.
