Comparison analysis of two different concentrated photovoltaic/thermal-TEG hybrid systems

Improved energy conversion of a photovoltaic module‐thermoelectric generator hybrid system with different cooling techniques: Indoor and outdoor performance comparison

“…In PV‐TEG cooling, the TEG is always underutilized as the temperature difference observed is less (≈3°C), which leads to very low efficiency (<1%). Hence, as reported earlier, 28,29 in‐field application of PV‐TEG combination must be rethought. Compared to conventional PV‐TEG hybrid system, TEG with concentrated PV is justified as reported in the literature 57‐59 …”

Maximum Power Point Tracking of Thermoelectric Generation Systems Under Nonuniform Temperature Distribution: A State-of-the-Art Evaluation

“…A study (Sato and Yamada, 2019) explored the different photovoltaic module cooling methods, which can provide a reference for cooling devices of the TEG system. Besides, utilization of waste heat can be improved by increasing heat flux through TEG; one effective way is to install heat pipes in TEG modules (Wen et al, 2021). Selecting a proper number of thermocouples and designing a reasonable structure of DC-DC converters are also crucial to make maximum use of the generated power by the TEG system.…”

Theoretical and experimental investigation of a photovoltaic/thermal panel partially equipped with thermoelectric generator under unstable operating conditions

“…The results of this study showed the high reliability of this system in such weather conditions. Wen et al, 39 in a numerical study, compared a linear Fresnel concentrating PVT system coupled with TEG (LF/PVT-TEG) with and without a gravity-driven heat pipe (GHP-LF/PVT-TEG) connected to the system. Although the electrical efficiency of GHP-LF/PVT-TEG was lower than the first system by 2.91%, their study shows that TEGs play an acceptable performance in the electrical output of the GHP-LF/PVT-TEG system and thermoelectric modules are suitable for working under high concentration ratios and high heat flux.…”
