摘要

本文通过建立混合PV-TEG系统的数值模型来进行研究。该模型考虑了温度对热电发电机所用建筑材料热电性能的影响。为了开展研究，对混合PV-TEG系统中的太阳能聚光、环境因素和对流换热系数、环境缓解和经济节约等变量进行了评估。结果表明，由于太阳能集中比的提高，混合PV-TEG系统的效率提高了4.65%。环境温度升高会导致系统效率降低1.74%。然而，风速的增加允许增加4.39%。较高的对流换热系数有利于混合PV-TEG系统的性能。采用这种技术可以减少0.45千克/小时的二氧化碳排放量，降低0.024美元/小时的经济成本。总的来说，混合PV-TEG系统被认为是无碳能源转型的一种策略。

Evaluation Through Numerical Modeling of the Performance and Economic Parameters in a Hybrid System with a Photovoltaic Cell and Thermoelectric Generator

The current investigation is carried out by constructing a numerical model to analyze a hybrid PV-TEG system. The model considers the influence of temperature on the thermoelectric properties of construction materials used in thermoelectric generators. For the development of the study, variables such as solar concentration, environmental factors and convective heat transfer coefficient, environmental mitigation, and economic savings in the hybrid PV-TEG system are evaluated. The results obtained demonstrate an increase of 4.65% in the efficiency of the hybrid PV-TEG system due to the improvement in the solar concentration ratio. Increased ambient temperatures can cause a 1.74% reduction in system efficiency. However, the increase in wind speed allows an increase of 4.39%. The higher convective heat transfer coefficient favors the performance of the hybrid PV-TEG system. Implementing this type of technology can lead to reductions in CO2 emissions by 0.45 kg/h and a decrease in economic costs by 0.024 USD/h. In general, the hybrid PV-TEG system is considered a strategy for the carbon-free energy transition.

期刊介绍： The International Review on Modelling and Simulations (IREMOS) is a peer-reviewed journal that publishes original theoretical and applied papers concerning Modelling, Numerical studies, Algorithms and Simulations in all the engineering fields. The topics to be covered include, but are not limited to: theoretical aspects of modelling and simulation, methods and algorithms for design control and validation of systems, tools for high performance computing simulation. The applied papers can deal with Modelling, Numerical studies, Algorithms and Simulations regarding all the engineering fields; particularly about the electrical engineering (power system, power electronics, automotive applications, power devices, energy conversion, electrical machines, lighting systems and so on), the mechanical engineering (kinematics and dynamics of rigid bodies, vehicle system dynamics, theory of machines and mechanisms, vibration and balancing of machine parts, stability of mechanical systems, computational mechanics, mechanics of materials and structures, plasticity, hydromechanics, aerodynamics, aeroelasticity, biomechanics, geomechanics, thermodynamics, heat transfer, refrigeration, fluid mechanics, micromechanics, nanomechanics, robotics, mechatronics, combustion theory, turbomachinery, manufacturing processes and so on), the chemical engineering (chemical reaction engineering, environmental chemical engineering, materials synthesis and processing and so on). IREMOS also publishes letters to the Editor and research notes which discuss new research, or research in progress in any of the above thematic areas.
