Dye-sensitized solar cell (DSSC) based on TiO2/SnO2 composite electrode has been fabricated. In this research, modifications TiO2 electrode in the form of composite TiO2/SnO2 which aims to optimize the process of transfer and charge separation that reduces premature recombination in the cells, so as to increase the conversion efficiency and stability of dye-sensitized solar cell performance. In this study, DSSC is composed of several components, among others, a semiconductor oxide, a layer of dye, a counter electrode, and an electrolyte. This study used three types of semiconductors at the working electrode is pure TiO2, composite TiO2/SnO2 and pure SnO2, electrolyte gel based polymer PEG with BM 1000, plate carbon as the counter electrode (cathode), and the use of dye from synthetic materials N-749 as dye sensitizer. This study tested with xenon lamp light source intensity of 100mW/cm2. Results of research and calculations showed that the DSSC based composite electrode TiO2/SnO2 better than the DSSC based pure TiO2 electrodes and based pure SnO2 electrodes, this is indicated by the value efficient as follows: 0.041%, 0.019%, and 0.0114%.
