Abstract

In this work, a new dye-sensitized solar cell (DSSC) was prepared using naphthol green B and Janus green B as photosensitizers and EDTA as reductant. A 210 μA of photocurrent and 1018 mV of photo-potential were generated using these dyes. The fill factor of 0.40, a conversion efficiency was observed to be 1.0028% and the power or maximum output of cell was calculated to be 213.78 μW. Because of the storage capacity in a cell, a DSSC can be used for a total of 180 min in dark. The properties of mixed photosensitize system EDTA-NGB-JGB were characterized and evaluated by UV-visible, fluorosencemeter, FESEM and XRD analysis. The photocurrent generation mechanism in photogalvanic cell was also discussed.
