Synthesis of TiO2/ZnO-Anthocyanin Hybrid Material for Dye Sensitized Solar Cell (DSSC)

Abstract Hybrid materials are composed of materials that have broad spectra absorption and can be added to other materials that improve their spectrum absorption. The characteristics of hybrid materials are the same characteristics as their constituent materials. When hybrid materials were added to organic compounds which combined with semiconductors, they can be used as photovoltaic applications. One of the most widely hybrid material research developments is its use as the solar cell. This research focused on TiO 2 /ZnO hybrid materials synthesis combined with anthocyanin as a pigment to determine the characteristics of the hybrid material obtained. In this research is to find the extent to which method applied that determines the success of the targeted hybrid materials formation. In the synthesis process for various ratios, TiO 2 and ZnO have been formed a composite material which shown by diffractogram of characteristic peaks of TiO 2 and ZnO and vibrations of Zn-O-Ti detected in FTIR spectra. Testing hybrid materials by using FTIR showed a C=O vibration of anthocyanin in material hybrid TiO 2 /ZnO-anthocyanin, than quality testing of hybrid materials was carried out using the DR UV-Vis instrument and was proved by enhancement of band gap energy between 3.2 to 3.3 eV
