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.
