Energy needs are increasing but the availability of fossil-based energy is increasingly depleting. The use of conventional energy has caused many problems, both for health and the environment. Researchers are looking for alternative energy that is environmentally friendly and can replace the role of fossil energy. One potential candidate that can be an alternative energy is thermoelectric. Thermoelectric devices are capable of converting heat energy and electrical energy directly. In this study, thermoelectric compounds with composite graphene oxide are formed. Graphene oxide is a modification of graphene that has low thermal conductivity. The composite method performed in this study is with a doctor blade. Research was conducted by variating GO concentrations, which are 0%, 5%, 10%, 15%, and 20%. Characterization is XRD, SEM, Seebeck coefficient & electrical conductivity. Results obtained in the thermoelectric performance test, CuS-GO with the largest concentration of 20%, has the largest Seebeck efficiency of 2737 μV/K. The result concluded that the addition of GO to CuS-GO material affects the increase in Seebeck material coefficient. © 2025 American Institute of Physics Inc.. All rights reserved.
