Natural dyes from red amaranth leaves as light-harvesting pigments for dye-sensitized solar cells
Source abstract
Abstract
Abstract This study reports red amaranth as a source of two natural dyes to be used as low cost sensitizers for wide bandgap semiconductors in dye sensitized solar cells. The two dyes were identified as Chlorophyll and Betalain from their characteristic absorption spectra. The photo electrochemical properties of dye sensitized solar cells using natural pigments containing Chlorophyll and Betalain was investigated in this work. The results indicate that the Chlorophyll dye shows a maximum photocurrent density of 1.3 mA/cm 2 with an energy conversion efficiency (η) of 0.53%. The Betalain dye showed a photocurrent density of 0.87 mA/cm 2 with energy conversion efficiency (η) of 0.23%. The better performance of chlorophyll dye as sensitizer for dye sensitized solar cells was supported by electrochemical impedance spectroscopy and bode plot measurements.
