Abstract
Dye plays a very important role in the Dye Sensitized Solar Cell (DSSC) application because the sunlight that comes in is captured and absorbed by dye. More light absorbed, the higher value of efficiency obtained. Therefore, dye plays a very vital role to increasing this efficiency value. For increasing the absorption of dye, this topic studied about effect of reduced graphene oxide (rGO) to DSSC Performance. its obtained through the hummers modified method which will be combined with dye in the ratio of wt% rGO-dye 0,1: 1; 0,3: 1; and 0,5: 1 respectively. Thickness Variation of rGO on the ITO transparent glass to enhance efficiency of DSSC also studied. The result show power conversion efficiency of the DSSC with the rGO-dye 0,1:1 (0,008%), rGO-dye 0,3:1 (0,019%), and rGO-dye 0,5:1 (0,0073%), which was higher than that of the DSSC without the rGO (0,0046%). ZnO nanorod as photoanode obtained by chemical bath deposition which is growth in temperatur 0 degree Celcius and Platina (Pt) as the counter electrode. SEM, UV-Vis and XRD were used to characterization of rGO and ZnO.
