Abstract
Codiaeum Variegatum Leaf (CVL) and Delonix Regia Flower (DRF) extracts were utilized as a photosensitizer, coated on the TiO2 nanorods (NRs) photo anodes in the dye sensitized solar cell (DSSC) fabrication and performance analysis. Current density-Voltage (J-V) analysis were performed to evaluate the photosensitization with CVL, DRF and mixed dyes, interestingly mixed dyes have shown improved performance owing to plausible mechanism of synergistic effect. The optimum power conversion efficiency (PCE) of the DSSCs having CVL and DRF dyes are 0.12 and 0.17%. Whereas enhanced PCE of 0.24% is achieved with mixed (1:1, v:v) CVL and DRF dyes based DSSC.
