Abstract
This research aims to examine the influence of the composition of TiO2 and ZnO as the working electrode on the efficiency of DSSC. The working electrode is prepared by depositing TiO2 and ZnO pastes on top of the FTO glass using the doctor blade method. The samples were then heated in an oven at a temperature of 250 ° C for 4 hours. In this study, three TiO2 / ZnO compositions were prepared and assembled into DSSC components with red spinach dye. SEM image shows that the composition of TiO2 / ZnO (0:2) produces the best surface morphology that is indicated by the number and aggregate uniform pores. This is consistent with the results of testing the electrical properties of the sample. The solar cell with the working electrode composed of TiO2 / ZnO (0: 2) yields an efficiency of 0.0515%, higher than the composition (2: 0) and (1: 1) which respectively yields 0.0044% and 0.0015%.
