Optimization of design parameter for a hybrid photovoltaic-thermoelectric system
The composite solar thermoelectric module is a combination of solar power generator using the effects of photovoltaic electricity and solar power generator using the photothermal field of solar energy using the wave properties of photovoltaic rays. In the case of solar power, if the heat of the panels collecting Photovoltaic increases, the efficiency of the generator decreases. Due to these problems, cooling systems are essential for solar power cells. The Hybrid Photovoltaic - Thermoelectric system is a system that leverages this wasted heat to increase efficiency. However, the efficiency temperature coefficient and the performance of thermoelectric modules differ depending on the length of the legs of the modular and the angle at which each leg forms during the design process. The ultimate purpose is to modify these geometries to make the optimal design of the solar thermocouple system. Therefore, the setting in this study shows temperature conditions that increase the length of thermocouples, the legs on which heat is transferred, to increase mechanical reliability or improve geometric shape. Furthermore, the stress on heat generated by the difference in thermal expansion caused by the thermoelectric generator is relatively stable compared to other modules, which results in a higher lifetime of the module itself. Based on the above findings, we attempt to design a module that represents optimal efficiency by approaching it as an aspect of geometric design modeling. The expected results of the project will be observed to increase the generator efficiency of the modulator as the temperature difference between the heating and cooling parts increases when the leg length of the modulator increases by a certain percentage. Furthermore, the geometric nature of Annular is expected to reduce von Mises Stress as the angle of the bridge and the center increases. As a result, it is expected to contribute greatly to the production of electricity.
