Dye Oriza sativa glutinosa doped Fe as a active element of Dye Sensitized Solar Cell (DSSC)

The aims of the research are to determine the effect of doping Fe (III) Sulphate into dye Oriza sativa glutinosa on the characteristics parameters of solar cells, to determine the optical characteristic, functional group and electrical characteristic of dye Oriza sativa glutinosa doped Fe (III) sulphate. TiO₂ nano size as much as 0.5 gr dissolved in 3 ml ethanol. 100 gr black sticky rice (Oriza sativa glutinosa) was immersed in 80 ml ethanol solution (95%) and kept at room temperature without exposing to light. Then it was filtered with a filter paper no.42, and the extracted result was process with chromatography. Furthermore, it was doped with Fe (III) sulphate respectively of 10^-1 M, 10^-2 M, 10^-3 M. The characteristic of dye solution was measured using UV-Visible Spectrophotometer Lambda 25 for absorbance, Elkahfi 100/I-V meter for conductivity amd Keithey 2602A for characterization of current and voltage (I-V). The result showed that the area of dye Oriza sativa glutionosa doped Fe (III) sulphate with concentration 10^-1 M the largest, because the value of V_oc intercept at 6.40 × 10^-1 mV and the value I_sc intercept at 1.89 × 10^-3 mA, with efficiency value is 0.148%.
