“…Furthermore, a conflict exists between the effect temperature has on both PV cell and TEG module. While the efficiency of the TEG module improves with higher temperature gradient resulting from higher concentration, the effect on the PV causes a reduction in efficiency and subsequently on the PV lifespan .

Summary Utilization of a broad range of solar spectrum has the potential for high power output from solar cells. However, solar photovoltaics (PVs) can convert only part of the solar electromagnetic spectrum into electricity efficiently. The remaining of the solar radiation is often dissipated in the form of heat, which causes performance reduction and reduces the life expectancy of the solar PV cell. Thermoelectric generators (TEGs) are devices that operate like a heat engine by converting thermal energy into electricity through thermoelectric effect. Integrating a TEG into a PV converter will enhance its efficiency and reduce the amount of heat dissipated. Different studies have been carried out and are still taking place to increase the total efficiency of a coupled photovoltaic thermoelectric generator (PV‐TEG) system. This review discusses the concept of PV converters and thermoelectric devices and presents the various models and numerical and experimental investigations on performance enhancement of integrated PV‐TEGs. The influence of key parameters on the performance of PV‐TEG were also discussed. The review is expected to serve as a reference to recent work on research and development of integrated PV‐TEG systems.

Nanofluid can be used in a CPV/T solar collector to boost electrical and thermal performances as this technology has drawn great attention from researchers over the last decades. In a CPV/T system, the amount of collected heat could be significantly higher than the amount of electrical power. Combining thermoelectric generator (TEG) and nanofluid-based CPV/T system may result in better electrical performance than CPV/T system alone. In the present work, a nanofluid-based CPV/T-TEG hybrid system with a cooling channel was designed and tested, and the obtained performance was compared with conventional cooling methods [ie, natural cooling (CPV/TEG) and water cooling (WCPV/T-TEG) methods]. At the optimum value of solar concentration, C = 14.6, the electrical performance of the nanofluid-based concentrated photovoltaic/thermal-thermoelectric generator (NCPV/T-TEG) configuration was found to be 89% higher than the standard PV modules.

On most dual fuel ships, the waste heat of engine exhaust gas and the cooling capacity of liquefied natural gas (LNG) in the fuel regasification process are not effectively used. In order to recover these redundant energy under the large temperature difference around 600 K, thermoelectric technology provides a feasible solution with the advantages of small size, no noise and high stability. In this article, a waste energy recovery system has been developed for LNG-diesel dual fuel ships using multistage thermoelectric generators (TEGs) scheme. According to the thermodynamic analysis and the materials selection, the recoverable energy, recovery form and thermoelectric materials used in the large temperature range of the dual fuel ship were determined. A multistage TEGs model considering the temperature distribution, fluid properties, connection methods and contact effects has been developed to predict the thermoelectric performance under the operating condition with large temperature difference. The results show that the maximum conversion efficiency can reach up to 18.54% with appropriate thermoelectric materials in different temperature zones and suitable multistage series-parallel schemes. Besides, the thermoelectric conversion effect makes the temperature distribution of the cold and hot fluids in the TEG quite different from that in the traditional heat exchangers. The output characteristics of TEGs are directly affected by the flow parameters of the cold and hot fluids and the connection methods of thermoelectric elements. This study provides a brand-new inspiration for developing the waste energy recovery and corresponding power conversion system on LNG-diesel dual fuel ships.
