CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
The quick growth of technology rises the urgency to introduce new alternatives for the sake of power generation. Thermoelectric power generation (TEG) technology is considered as one of the main processes which generates electrical current directly from a temperature difference. The thermoelectric effect gives the most positive method to produce electricity out of radioisotope power. It is called radioisotopic thermoelectric generator (RTG) employed in Micro-Electromechanical Systems (MEMS) regularly. Therefore, thermoelectric power generation can be considered as one of the reliable power generation technologies as well as photovoltaic one. One of the advantages of thermoelectric systems is that there is no requirement for moving devices such as solution pumps, compressor, and valves since no working fluid is utilized in such systems. Moreover, it also has a high-precision temperature control. This issue proves that TEGs, coolers, and heat pumps have supremacy over conventional power generation as well as cooling and heat pumping applications. Lack of moving equipment leads to surging in reliability and lifetime as well as declining of operation and maintenance costs. The modularity provides a wide variety of utilization without considerable weakness in performance. In addition, hazardous environmental damages are prevented due to the lack of fluid in its working principles.
Currently, thermoelectric technology has been facing challenges in efficiency and physical property promotion in relation to the performance of thermoelectric materials and a comprehensive review of thermo- electric studies can address this issue.
The aim of present work is to conduct a comprehensive review in the fields of thermoelectric technology, materials, and applications to obtain insights about thermoelectric concept regarding current obstacles and challenges.

- Carefully place the TEG module between the heat source and heat sink, ensuring good thermal contact on both sides.
- Insulate the TEG Module:
- Surround the sides of the TEG module with insulating material to minimize heat loss and improve efficiency. Make sure not to cover the hot and cold sides completely to allow airflow.
- Connect the Electrical Wires:
- Attach electrical wires to the positive (+) and negative (-) terminals of the TEG module using solder or clamps.
- Connect the other ends of the wires to a multimeter or directly to the load you wish to power.
- Test the Output:
- Heat the hot side of the TEG module using the heat source.
- Monitor the voltage and current output using the multimeter. Be cautious of the temperature to avoid damaging the TEG module.
