ABSTRACT

Dye-sensitized solar cells (DSSC) based on natural sensitizers have become a topic of significant research because of their importance in the field of energy conversion. In our study we have used curcumin and aminothymoquinone as natural dye sensitizers. Aminothymoquinone is an important constituent of Nigella Satvia. It is very important light sensitizer. The dye molecules are absorbed by TiO2nanoparticles at the surface, when submerged in the solution for 24 hrs. When illuminated under 80W/cm2 intense light the photovoltaic properties were investigated and the current density-voltage characteristics and current conversion efficiency measurements were carried out. The short-circuit current (Isc), open circuit voltage (Voc), Fill factor (FF) and efficiency (η) for both the dyes were determined. Comparatively the aminothymiquinone dye as light harvesting material was found to be a more promising candidate for future solar cells. Further being natural dyes both these have minimum impact on the environment.
