Abstract
In this work, we consider the fabrication method and electrical characteristics of dye-sensitized solar cells (DSSCs), which use titanium (Ti) metal thin films to replace expensive fluorine tin oxide (FTO) electrodes. The thickness of the Ti thin film was changed by adjusting the deposition time of the Ti, and the surface resistance decreased as the thickness of the Ti thin film became thicker. The thickness of the Ti thin film was shown to be similar to the surface resistance of the FTO thin film at approximately 190nm and the DSSC with a thickness of approximately 250nm showed the highest energy conversion efficiency of 4.24%. Furthermore, the possibility of commercialization was confirmed by fabricating and evaluating the DSSC module.
