Effect of Dye Sensitized Solar Cell Fabricated with Different Thickness of Rutile-Anatase TiO₂ Electrode on the Electrical Performance

Abstract

DSSC is in the third generation of PV technology which employ easily available raw material with low cost manufacturing methods. Dye- Sensitized Solar Cell (DSSC) consist of a photo electrochemical cell of oxide semiconductor layer, dye molecules, electrolyte and counter electrode. This paper presents the comparison of the thickness of the TiO2 using Rutile-Anatase composition at 1:4 ratioto the electrical performance of the DSSC. The Dr. Blade method was employed to the fabrication of the DSSC with a reference dyes and platinum sputtered technique counter electrode. The result shows that solar cell with an efficiency of 0.36 % of was produced from electrode film thickness of 10 µm. Further increase in the thickness shows decreased of the efficiency, especially the short circuit current. From the experiment conducted, it shows the 10 µm is suitable size to fabricate the DSSC using the RA-TiO2 but further investigation is needed to verify the electron transfer efficiency and recombination rate in thicker/thinner films.
