Abstract:
-The experiment studied on the effect of TiO2 photoanode thickness and the quantity of MWCNT counter electrode in the performance of dye- sensitized solar cells. In fabricating the DSSC, iodide/triiodide under acetonitrile solvent was prepared as electrolyte solution and cis- bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)-ruthenium(II) dye (N3) was used as sensitizer. The two factors were studied using 32 full factorial method design. Three different TiO2 photoanode film thicknesses were combined with three different amounts of MWCNT counter electrodes. The samples were characterized by SEM and UV-Vis spectroscopy to investigate the microstructure of the TiO2 film and the optical properties of the film in conjunction with the dye. Based on the maximum power obtained for the different combinations, the optimum combination of TiO2 photoanode film thickness and MWCNT counter electrode quantity was known.The optimum combination of photoanode thickness and counter electrode quantity was the cell with three TiO2 film layers and 500 mg of MWCNT per 10 mL of solvent.It yielded 0.075 % efficiency under sunlight. The maximum powers which were dissipated by the fabricated cells were subjected to ANOVA and were used for analysis of the significant factors and interactions.
