N2 - This research is aimed to obtain the optimum thickness of a transparent TiO2 as scattering layer to improve the efficiency of Dye-Sensitized Solar Cell (DSSC). TiO2 layer was formed on FTO substrates using spin coating method. The working electrode consisted of TiO2 nanopowder layer and transparent TiO2 layer. The thickness of transparent TiO2 was varied from 1 to 7 layers. The thickness of the transparent TiO2 layer was determined by Dektak profilometer. The absorbance of TiO2 was characterized using Spectrophotometer UV Visible Lambda 25. The characteristics of electrical properties I-V were measured using Keithley I-V Meter 2602A. As results, the thickness of TiO2 nanopowder layer was 13.63 μm and the thickness of TiO2 nanopowder with 1-7 transparent TiO2 as scattering layers were 16.14 μm, 19.65 μm, 22.36 μm, 26.22 μm, 29 μm, 32 μm and 35 μm. Moreover, from absorbance characterization, it showed that transparent TiO2 layer had higher absorption than TiO2 nanopowder layer. The absorbance of TiO2 after soaking in dye Ruthenium N719 increased with the addition of 1-7 layers of scattering layers. The highest efficiency of DSSC was obtained at the sample with 5 layers of transparent TiO2 i.e. 0.22 %.
