Abstract
This research was aimed to invent and test the conversion efficiency of dye sensitized solar cell (DSSC) from N719 dye with varied the concentration of N719 dye at 0.20, 0.40, 0.60, 0.80 and 1.00 mM. The working electrode of this DSSC was made of TiO2 (anatase phase) while the counter electrolyte was made of Pt. The EL-HPE electrolyte was used for this DSSC. Measurement the conversion efficiency via Peccell PEC-11 solar simulator, It found that the efficiency of dye-sensitized solar cells at a concentration of 0.20 mM has 0.62%. While, at the concentrations of 0.40, 0.60, 0.80 and 1.00 mM, the efficiencies have 0.54%, 0.18%, 0.12% and 0.27% respectively. This effect is likely to be related to the fast recombination of the carrier ions of the dye when the concentration increases.
