In general, a photoelectrode in DSSC(dye sensitized solar cell) are fabricated by using the TiO2 (Titanium dioxide) to realize high efficiency and the efficiency of DSSC is affected by the size, the shape and the property of TiO2. We synthesized the crystalline TiO2 by sol-gel method. In spite of many merits, only weakness for the sol-gel method is taking many process times. To solve this problem, we reduced the fabricating processes. The reduced process is the making process that is TiO2 sol to TiO2 powder with including of two heat treatment and two mixing. We could simplify the process by preparing TiO2 sol to TiO2 paste directly. As a result, DSSC fabrication process is simplified and we have obtained the efficiency best result 3.88% with VOC=0.71 V, JSC=8.70 mA/cm-2, and FF=62.37%, respectively.
