Abstract

In this study, semi-flexible dye-sensitized solar cell (DSSC) and flexible DSSC are examined comparatively. First, TiO2 paste with HCl was prepared and flexible photoanodes were produced by coating this paste on the indium tin oxide-coated poly(ethylene terephthalate) (ITO/PET) flexible substrates under the same conditions. These flexible photoanodes have been sensitized with Ruthenizer N719 dye at room temperature for 48 h. The Pt was used as the back-electrode. The first back-electrode was fabricated for semi-flexible DSSC by spraying Pt on the fluorine-doped tin oxide (FTO). The second back-electrode was fabricated for flexible DSSC by coating Pt on ITO/PET using the chemical reduction method. The flexible photoanodes and Pt counter-electrodes have been combined. The photovoltaic performance of the semi-flexible DSSC was compared to the flexible DSSC.
