Natural Pigments from Plants Used as Sensitizers for TiO2 Based Dye-Sensitized Solar Cells
Figure 6
Photocurrent-voltage (J-V) curves for the DSSCs sensitized by four kinds of natural dyes: (a) teak, (b) tamarind, (c) eucalyptus, and (d) bottle brush under visible light illumination of intensity 256 mW/cm2 (electrolyte composition: 0.2 M LiI, 0.02 M I2 in propylene carbonate). Curve (e) is the same for bare TiO2 electrode.
