Abstract

In this study, a transparent conductive oxide (TCO)-less dye-sensitized solar cells (DSSCs) was fabricated by using titanium (Ti) electrode to replace the Fluorine-doped tin oxide (FTO) for the reduction of manufacturing cost. Ti film was formed by electron beam evaporation method and the results showed the sheet resistance of Ti electrodes with a thikness of 500 nm similar to FTO. In case of power conversion efficiency (PCE), a DSSC with Ti electrodes showed a lower value than that with FTO by 0.38%. For the investigation of the difference, the DSSCs were measured and analyzed by using electrochemical impedance analyzer (EIS).
