Introduction

In today's world, the search for alternative energy sources is becoming increasingly urgent due to the growing energy demands. One potential solution is the utilization of heat energy that is usually wasted. With advancements in technology, there is now a semiconductor component that can convert heat energy into electrical energy. One of these components is the Peltier element, also known as the thermoelectric Generator (TEG). This element operates by utilizing the effects of Seebeck and Peltier, which converts the temperature difference between the hot side (hotide) and the cold side (coldside) into electrical energy. Likewise, electrical energy can create temperature differences on both sides of this element.

Background and Literature Review

The use of thermoelectric generators has gained significant attention in recent years due to their potential to convert waste heat into electrical energy. Thermoelectric generators have been widely used in various applications, including power generation from industrial heat waste, space exploration, and renewable energy systems. The TEC1-12706 is a commercial thermoelectric generator that has been widely used in various applications. However, there is a lack of research on the characteristics of this generator, particularly in terms of its thermoelectric properties.

Methodology

In this study, the main focus is to analyze the thermoelectric characteristics of the TEC1-12706 type generator. The study was conducted with a single configuration, two elements arranged in series, and two elements arranged in parallel. The test results were used to derive equations that describe the thermoelectric characteristics of the TEC1-12706 in conditions without load or with the influence of temperature difference (ΔT) on open voltage (VOC) and current (I).

Results

The equation found for the open voltage (VOC) is as follows:

Single Configuration: VOC = 0.0275ΔT - 0.036
Two series: VOC = 0.0513ΔT - 0.046
Two parallel: VOC = 0.0253ΔT - 0.0203

Meanwhile, the effect of temperature difference (ΔT) on current (I) is also examined, and the equation is obtained:

Single Configuration: I = 0.0046ΔT + 0.0017
Two series: i = 0.0054ΔT + 0.0043
Two parallel: i = 0.0057ΔT + 0.0039

Discussion

Through this characteristic analysis, it can be estimated that the ability of the thermoelectric elements of the TEC1-12706 type in producing electrical energy from wasted heat. In the context of energy harvesting (energy harvesting), the selection of elements configuration greatly affects the efficiency of energy conversion. For example, the configuration of two elements arranged in series shows a significant increase in open tension compared to a single configuration. This is caused by the effect of the voltage accumulation of each element that contributes to the final result.

On the other hand, the configuration of two elements in parallel is superior in terms of currents produced. This makes parallel configuration more efficient in situations where current needs are more important than voltage. This consideration is important for practical applications, such as in the power generation system from industrial heat waste, where the choice of appropriate configuration can improve the overall performance of the system.

Conclusion

In conclusion, the analysis of the characteristics of TEC1-12706 provides valuable insights for the development of heat energy harvesting technology. By utilizing this element efficiently, we can help reduce energy waste and create sustainable alternative energy sources. In the future, further research and innovation in the design of the energy harvester system are expected to encourage broader adoption of this thermoelectric technology.
