Abstract
This study aims to develop a thermoelectric generator using ZnO as a semiconductor material. It will use ZnO as one component and Cu-doped ZnO (ZnO:Cu) as the complementary component. The ZnO:Cu samples were synthesized using the sol-gel method followed by a pelletizing process. Characterization techniques included XRD to analyze phase formation, FTIR to identify functional groups, UV-Vis spectroscopy to determine band gap energy, and SEM to observe particle shape and distance between particles. In addition, the electrical performance of the TEG was evaluated by measuring the output voltage under temperature variations. The results indicate that Cu doping in ZnO is integrated into the ZnO lattice. Additionally, Cu doping lowered the band gap energy from 3.28 eV (pure ZnO) to 2.65 eV (ZnO:Cu). This change also affected the crystal structure and shape of ZnO, which may improve its properties as a semiconductor material for thermoelectric applications. Voltage measurements at temperatures of 40°C, 50°C, and 60°C showed average values of 0.7 mV, 1.1 mV, and 1.4 mV, respectively. The highest voltage occurred at 60°C. The optimal Seebeck coefficient was also measured at 60°C, ranging from 0.05 to 0.06 mV/°C.
