N2 - TiO2 semiconductor materials as working electrodes are commonly used in DSSC fabrication. One type of TiO2 used in DSSC fabrication is a paste form. In this study aims to determine the effect of the viscosity level of TiO2 paste. The deposition of a TiO2 transparent thin film using spin coating method with 450 °C heating temperature. Preparation of TiO2 paste was done by mixing TiO2 and ethanol by comparison (1:1, 1:3, 1:5). DSSC fabrication is characterized by an I-V test to determine the efficiency value. Sweet potato dyes used from the anthocyanin type. Preparation of sweet potato dye by mixing the sweet potato into a mixture of solution between methanol, distilled water, and acetic acid with the ratio of solution (1:3:5). UV-Vis spectrophotometer characterized the results of sweet potato extraction. In the test results I-V the most significant efficiency value is obtained at a 1: 1 ratio with an efficiency value of 1.92 x 10-2 and the absorbance peak obtained at 532 nm wavelength.
