Introduction

The world is shifting towards renewable energy sources to reduce our reliance on fossil fuels and mitigate the effects of climate change. One promising area of research is thermoelectric energy conversion, which harnesses waste heat to generate electricity. The Peltier element, a thermoelectric device, has gained significant attention in recent years due to its potential to convert thermal energy into electrical energy. In this study, we characterized the Peltier TEC-12706 element to explore its capabilities as a thermoelectric generator.

What is the Peltier TEC-12706 Element?

The Peltier TEC-12706 element is a thermoelectric device that utilizes the Seebeck effect to convert thermal energy into electrical energy. When an electric current flows through it, this element can move heat from one side to the other. In the context of this study, the focus is on its ability to produce electricity from temperature differences. The Peltier element is commonly used for cooling and heating applications, but its potential as a thermoelectric generator has not been fully explored.

Research Methodology

This study involved strict temperature regulation on the cold side while applying temperature variations on the hot side. The application of this condition is crucial to maximize the potential for the conversion of energy from heat to electrical energy. By using thermocouples, accurate temperature measurements were carried out to ensure that the temperature difference (ΔT) between the two sides was significant. This is a critical factor in determining the efficiency of energy conversion.

Tools and Sensors Used

To characterize the Peltier TEC-12706 element, we employed the following tools and sensors:

Thermocouple: This tool is used to measure the temperature on both sides of the Peltier element. Accurate temperature measurements are essential for further analysis.
ACS-712 Current Sensor: This sensor is used to measure the output current of the Peltier element. High current values indicate that the elements work well in converting thermal energy into electricity.
Voltage Sensor: In addition to measuring current, the voltage sensor is used to see how much the voltage is produced by the element. The combination of these two parameters helps in calculating the maximum power that can be produced.

Results and Analysis

Through the tests conducted, we obtained data that the Peltier TEC-12706 element is capable of producing a significant maximum power at a certain temperature difference. The resulting power value is very dependent on the magnitude of ΔT. The greater the temperature difference between the hot side and the cold side, the higher the power that can be produced. These results indicate the great potential of the Peltier element in the application of energy conversion, especially in the context of utilizing unused heat sources.

The results of this study demonstrate the potential of the Peltier TEC-12706 element as a thermoelectric generator. The device's ability to convert thermal energy into electrical energy makes it an attractive option for renewable energy applications. However, further research is needed to optimize the performance of the Peltier element and to explore its potential in various applications.

Conclusion
