“…In this work, the thermoelectric cell functions as a cooling device, usually found in the literature as Thermoelectric Cooler (TEC). When the temperature of the cell increases, its efficiency decreases, the thermoelectric cooler (TEC) placed under the cell will cool it when an electric current I is applied on this TEC [21,24]. The cold side of the thermoelectric cells will be connected to the panel, so it can remove the heat through the contact with the back of the panel.…”

“…The thermoelectric cell is capable of transferring heat between its sides when electric power is supplied to its terminals. A thermoelectric effect is a physical phenomenon consisting of the direct conversion of heat into electrical energy (Seebeck effect) or inversely from electrical current into heat (Peltier effect) without moving mechanical parts [15,20,21]. The information collected during the experiments are: Open circuit voltage; Short circuit current; Generated power; Panel temperature; Peltier cell power.…”

“…These characteristics have made photovoltaic solar energy expand around the globe in recent decades, relying on private sector investments and public sector incentives for its adoption in the most diverse regions. Among the disadvantages of photovoltaic generation are: Intermittence, when the panels do not generate energy at night and produce less in shading conditions, such as cloudy weather; Solar panels require inverters to connect them to the grid or batteries or other storage if operating in isolated systems; Unfortunately, 80% of the solar irradiation absorbed by the PV cell is not effectively converted into electricity [21] The efficiency of solar panels is low when compared to other forms of generation, hovering around 20%. [22] The residual illumination is dissipated as heat causing losses in the power output of the solar cell.…”

“…[22] The residual illumination is dissipated as heat causing losses in the power output of the solar cell. [21,22] Therefore, the efficiency depends mostly on sun radiation and operating temperature of its cells. Solar radiation is associated with the amount of sunlight available to the photovoltaic panel, so that its maximum production point theoretically corresponds with the point where the cell receives maximum incidence.Therefore, radiation and efficiency have a directly proportional relationship.…”

Photovoltaic solar energy has been growing due to the demand for diversification of the global energy grid and the concern about replacing fossil fuels with renewable energy. There is a great potential for this form of energy generation due to high levels of solar irradiation. However, the efficiency of commercial panels is still low and is negatively affected by temperature rises on the panel. To mitigate this effect, several cooling techniques have been previously proposed. This work focuses on studying the relation between the temperature of solar panels and the energy produced by them. It also uses thermoelectric cells acting as coolers for the system bringing down the panel temperature to increase its efficiency. The main goal is to build a plant consisting of a solar panel attached to one or more thermoelectric cells and connected to a data acquisition system. This setup will be used to evaluate the improvement in performance obtained through this strategy. The experiments will be carried out at the Petroleum Measurement Evaluation Laboratory - LAMP, and the results will be compared with mathematical and simulation models present in the literature.

“…PV-TEG system supplying a synchronous reluctance motor was simulated with DC-AC/MPPT instead of using DC-DC/MPPT converter in [21]. Cascaded TEC and TEG have been modeled for cooling and improving the power output of PV cells whose waste heat has been pumped with the TEC and converted to electrical power with the TEG were modeled in [22]. The waste heat of an exhaust system was recovered by TEG and this energy was used to supply TEC for PV panel cooling to get auxiliary electrical energy for hybrid cars in [23].…”

Bidirectional Modeling of Thermoelectric Module Using MATLAB/Simulink for Circuit Simulations

This paper presents a complete model for thermoelectric modules (TEMs) in order to be used in circuit simulations in MATLAB/Simulink software. The purpose of this study is to develop a single block like other circuit elements in the Simulink library by combining both thermoelectric generator (TEG) and thermoelectric cooler (TEC) module parameters and their operations. Since TEG and TEC are both thermoelectric devices, mostly whose main material, such as Bi 2 Te 3 , is the same for similar temperature ranges, a TEG can be operated as TEC and vice versa a TEC can be operated as TEG. In some systems, such as PV-thermoelectric (TE), fuel cell-TE, and battery temperature management of electric vehicles, the modules can be used in both modes. Also, in some cases of these systems, sometimes the TEM may need to be operated as a generator, and sometimes as a cooler. The bidirectional operation of the TEM is a costsaving approach since the 2 types of TEMs are not needed to be installed together. This paper proposes a novel model whereas the studies up to date in the literature have not been fully compatible with the bidirectional usage of the modules. The proposed model deals with the polarities of both the thermal and the electrical ports of the TEM in order to decide the mode of operation, that is TEG or TEC. Maximum parameters and performance parameters for both TEG and TEC operations are included in the module block so as to observe and control the device for desired operating conditions. It is seen that the simulations with the temperature-dependent parameters have given very close results to the graphics of the datasheet. However, simulations in which the Thomson heat isn"t ignored have more deviations compared to the datasheet. Moreover, the simulations with the constant material properties have given better results than the Thomson heat included ones in the cases of the higher ∆T levels. While ∆T is 10 °K, COP max without the Thomson heat has been found as 3.399 which is the same as the datasheet. Meanwhile, COP max with the Thomson heat has been found as 3.7147, and COP max with the constant properties has been found as 3.8057. However; while ∆T is 50 °K, COP max is 0.247 without the Thomson heat which is the same as the datasheet, but COP max is 0.341 with the Thomson heat, and COP max is 0.268 with constant material properties. In addition, it is shown that, under variable polarities of thermal and electrical ports, bidirectional operation of the TEM is successfully achieved and the TEM is operated as both TEG and TEC in the same simulation.
