Comparative study of natural anthocyanins compound as photovoltaic sensitizer

Fabrication and characterization of different natural dyes extracts of dye sensitized solar cell (DSSC) are reviewed in this paper. Inorganic metal complex, N3 dye is also studied as a comparison. The paper focussed on the performance of sensitization which is related to the interaction between dye and TiO2 surface. The electrical performances of the cell such as short circuit current density (JSC), open circuit voltage (VOC), fill factor (FF), and overall conversion efficiency (η) was also investigated via current-voltage characteristic measurement as well as light absorption of dye loaded on TiO2 film. The resultant study showed that higher ratio of active compound and higher interaction of dye-TiO2 will results in higher conversion efficiencies.
