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 TiO2/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, TiO2 and ZnO have been formed a composite material which shown by diffractogram of characteristic peaks of TiO2 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 TiO2/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

Structural and Optical Characteristics of Multilayer ZnO Nanorod:TiO2 by DC Magnetron Sputtering for Dye Sensitized Solar Cell (DSSC) Application

“…The denser the pores will result in a decrease in the ability of the electrolyte to penetrate the membrane so that the transfer of electrons from the electrolyte to the photosensitizer becomes slower. This condition will result in lower DSSC efficiency values [21].…”

“…Intensive studies carried out on ZnO have led to the synthesis of various morphological structures from 1D to 3D Intensive studies conducted on ZnO have led to the synthesis of various morphological structures from 1D to 3D [5], leading to their use in numerous applications such as solar cells [6][7][8][9], photo-catalysis [10][11][12], photoelectrochemical (PEC) water splitting [13,14], self-cleaning surfaces [15], supercapacitor [16], sensors and biosensors [17,18]. The synthesis of ZnO is based on different manufacturing processes including sputtering [19], spray pyrolysis [20], hydrothermal [21], sol gel [22] and electrodeposition [23,24].…”
