Abstract
In general, Dye-sensitized Solar Cells(DSCs) consist of the nanocrystalline titanium dioxide($TiO_2$) layer which is fabricated on a transparent conductive oxide(TCO) layer such as $F/SnO_2$ glass, a dye adhered to the $TiO_2$, an electrolyte solution and platinum-coated TCO. Among these components, two TCO substrates are estimated to be about 60% of the total cost of the DSCs. Currently novel TCO-less structures have been investigated in order to reduce the cost. In this study, TCO-less DSCs consisting of titanium electrodes were investigated. The titanium electrode is deposited on top of the porous $TiO_2$ layer using electron-beam evaporation process. The porosity of the titanium electrode was found out by the SEM analysis and dye adhesion. As a result, when the thickness of the titanium electrode increased, the surface resistance decreased and the conversion efficiency increased relatively.
