【 摘 要 】

The aims of the research to were know performance of DSSC using the dye of Zingiber, Cinnamomum, Curcuma, and Oryza as a photosensitizer with a variation of dye deposition area with spin coating techniques. The structure of the samples as a sandwich consisting of the working electrode (TiO2), dye, electrodes of platinum (Pt) and the electrolyte sandwiched between two electrodes. Test absorbance dye using UV-Visible Spectrophotometer Lambda 25, using a two-point conductivity test probes El Kahfi 100 and characterization test IV using a Keithley 2602A. For Zingiber results showed that absorbance at 243 nm and 279 nm, photoconductivity of 0.29 Ω-1m-1and the efficiency is 0.015% on 0.5 cm2. Cinnamomum results showed that absorbance at 253 nm and 403 nm, photoconductivity of 0.11 Ω-1m-1and the efficiency is 0.002% on 3 cm2. Curcuma results showed that absorbance at 243 nm and 422 nm, photoconductivity of 0.177 Ω-1m-1and the efficiency is 0.072% on 3 cm2. Oryza results showed that absorbance at 240 nm and 423 nm, photoconductivity of 0.21 Ω-1m-1and the efficiency is 0.04% on 2.25 cm2. Best absorbance value was obtained from Oryza dye; the highest photoconductivity was obtained from Zingiber dye, and the highest efficiency was obtained from Curcuma dye.
