Dye-sensitized Solar Cell (DSC) is one of the noteworthy devices due to its superior decoration and low cost process. However, there is a drawback in low conversion efficiency. Therefore we have studied fabrication method of the TiO₂ films for the improvement of the conversion efficiency. In this paper, we report on a method how to improve the conversion efficiency due to optimizing TiO₂ layers using the electrostatic inkjet. It was found that density of the TiO₂ layer is controlled by changing gap length between the two electrode by a scanning electron microscope of the inside and interface of TiO₂ layers. Further, the conversion efficiency of the cell was slightly enhanced by the stack of the two different density layers.
