Summary To realize the broad energy utilization, a novel combined system mainly consisting of a dye‐sensitized solar cell (DSSC), a thermoelectric generator (TEG), and a thermoelectric cooler (TEC) is proposed. The heat released by the DSSC is partially utilized for TEG to generate electricity, thereby driving the TEC for cooling. Considering diverse irreversible losses of the system, the power density, energy efficiency, and exergy efficiency of the coupled system are discussed concretely. In the TEG‐TEC current working range, when the power density or efficiency increase rate of the integrated model reaches a maximum, the corresponding power density, energy efficiency, and exergy efficiency are 38.439 W m−2, 13.21%, and 28.34%, respectively, which are 4.42%, 4.43%, and 4.38% higher than those of the DSSC alone. Comprehensive sensitivity analyses are performed for figuring out how the proposed system performance changes with the variation of main operating conductions as well as design parameters of DSSC and TEG‐TEC. Finally, owing to the Thomson effect in TEG‐TEC, the conclusions got here indicate that energy efficiency and power density about this combined model are reduced by 33.28% and 33.22%. Derived conclusions reveal that the established system is appropriate, which may supply new insights into the majorization of such a functional coupled system.

“…Bajo este contexto es necesario explorar de manera urgente nuevas fuentes de energía renovables, las cuales tienen numerosas ventajas, entre ellas su fácil obtención y que no causan contaminación (Hepbasli, 2008). Entre las nuevas fuentes exploradas, la energía solar ha sido objeto de estudio durante las últimas décadas debido a las ventajas que presenta por ser abundante, pura y libre (Zhang et al, 2022). Pero los sistemas de energía fotovoltaica también presentan desafíos importantes al sistema de suministro, una de las características es que la fuente presenta variabilidad incontrolable, no es posible garantizar las condiciones ambientales con antelación (Joshi et al, 2009b) (Saitoh et al, 2003).…”

Debido a las limitaciones que presentan las baterías y los supercondensadores es necesario la hibridación de batería y supercondensadores y aprovechar las ventajas que presentan de forma independiente, las baterías tienen una alta relación de almacenamiento de energía y por otro lado los supercondensadores pueden proporcionar altos niveles de potencia. En esta investigación se desarrolló una simulación en el software Matlab/Simulink un sistema fotovoltaico de 8 paneles solares en serie, con un sistema de almacenamiento híbrido que contaba con 18 supercondensadores en serie con un voltaje de 300V y una capacitancia de 995F y 1 batería con un voltaje nominal de 240V, evaluando, el voltaje de funcionamiento de la matriz fotovoltaica se obtuvo con el algoritmo de seguimiento del punto de máxima potencia (MPPT). Se demostró que la hibridación presentó mejorías en el sistema de almacenamiento, el supercondensador actúa como amortiguador logrando extender la vida útil de la batería.

“…Thermoelectric modules (TEM) have attracted substantial attention as non-vapor compression refrigeration technologies to prevent global climate changes and ozone layer depletion [1][2][3][4]. Their advantages include fast response, compact size, no noise, no vibration, and no moving parts without a refrigerant that can be used for heating, ventilation, air-conditioning, and refrigeration (HVAC&R) [5][6][7][8][9]. TEM has been studied as a solid-state heat pump based on the Peltier effect since the early 2000s [10].…”

Thermoelectric technology has been developed as a substitute for existing refrigerants in heating, ventilation, and air-conditioning system applications for building decarbonization. A hydraulic thermoelectric radiant cooling panel (hTERCP) operated based on the Peltier effect can alternate a conventional cooling system using a chiller with refrigerators. This study aimed to develop a cooling performance prediction model for a hTERCP-integrated free cooling system according to the desirable range of five design factors. A mockup model of the hTERCP was constructed and tested in an environmental chamber to verify the proposed simulation model. The simulation and the experimental analysis confirmed that the heat rejection performance of the thermoelectric module (TEM) significantly affects the cooling performance of the hTERCP. The cooling water temperature was the primary design factor for releasing heat from the hot side of the TEM and significantly influenced the cooling performance of the hTERCP. A parametric analysis of the five design factors was conducted to investigate a method for improving the coefficient of performance (COP) of the hTERCP. The cooling water temperature affected the COP by 38.6–45.7%, and the heat exchange area of the cooling surface greatly influenced the cooling performance by 41.4%. The cooling water flow rate, heat exchange effectiveness of the water block, and heat resistance of the hot side were confirmed to have relatively little influence as 9.7–10.2%, 11.9–24.8%, and 0.7–11.1%, respectively.
