Abstract—In this paper, we propose fabricating method of high quality titanium oxide (TiO
2) thin film for Dye-Sensitized Solar Cell (DSSC) by Electrophoresis Deposition (EPD). We focused on stirring time of solution, multilayer thin film and addition of EPD solution. Stirring time of solution was conducted for 1, 3, 6, 12, 24, 48 hours, and multilayer thin film was fabricated three types (single, double, four layer). Addition of EPD solution was adopted polyethylene glycol (PEG). The amount of PEG was conducted five types (0, 5, 15, 35 and 50 g/L). MK2 dye which is organic dye was used as photosensitizer. As a result, the highest conversion efficiency was obtained at 4.12% with stirring for 24 hours, four layers and 5g/L PEG.
Index Terms—Dye-sensitized solar cells (DSSC), electrophoresis deposition (EPD), MK2-dye, stirring time, multilayer thin film, polyethylene glycol (PEG).
