Finding the most optimal configuration of hybrid concentrator photovoltaic (CPV)-thermoelectric power generator (TEG) system integrated with a microchannel heat sink (MCHS) is of great importance to achieve the best performance. Thus, two different hybrid configurations were chosen for the study including CPV/TEG/heat sink and CPV/heat sink/TEG. In addition, the performance of both hybrid configurations was compared with standalone CPV/heat sink and TEG/heat sink. In the conventional hybrid design, the TEG was directly attached to the back surface of the CPV module, whereas the other side of the TEG was integrated with MCHS. In the new hybrid design, the MCHS was sited between the CPV and the TEG module as both sides were subjected to concentrated solar radiation. Effects of varying the simulated solar

“…The configuration of the HS is also very important. HS studied by [25] proposed to have two systems, a CPV/STC and a TEGS/STC which are placed side by side. This configuration exploits the maximum irradiance for both CPV and TEG but double the surface of the HS.…”

The solar energy is increasingly used as a renewable energy source. Raising the efficiency of energy conversion from solar to useful energy (electric and thermal) represents an important research direction in the renewable energy domain. Using hybrid systems for electric and thermal energy cogeneration can be a solution. In this study, a hybrid system (HS) is designed, manufactured, implemented, and experimentally tested under concentrated sunlight with a concentration ratio of 25 suns, obtained using a Fresnel lens as a sunlight concentrator. The HS comprises of four concentrated photovoltaic cells (CPVs), four thermoelectric generators (TEGs), and a solar thermal collector (STC). The HS is studied in three configurations of the exposed surface: only the CPV active area, the CPV active area with ceramic support, and the CPV active area with ceramic support covered with graphite sheet. Results reveal that the efficiency of each system component is affected by the exposed surface. If the efficiencies of the CPVs decrease from 32.3% to 30.8% from the first configuration to the last one, the efficiencies of TEGs and STC increase from 0.12% to 0.44 and from 26.3% to 52.0%, respectively. Increasing the concentration ratio from 25 to 33 suns, the power of the CPVs increases with almost 31%, but the efficiency decreases slightly, instead the efficiencies of the TEGs and STC increase.

Summary The photovoltaic‐thermoelectric hybrid system (PVTE) is less sensitive to the photon wavelength than the pure PV system. This phenomenon can make the PVTE to be a good method of obtaining electrical energy from solar energy. A challenge of this system is how to distribute the energy in the working process. To solve this problem, this paper establishes a thermodynamic model to study the energy matching mechanism of the hybrid system. The influence of dynamic solar radiation has been considered in the model. The result indicates that the relationship between the PVTE efficiency and the PV bandgap looks like a “reverse U" (rises first and falls later). The impacts of the optical concentration ratio and the TE parameters on the optimal PV bandgap are studied. No matter how these two parameters change, the optimal PV bandgap of the PVTE is around 1.15 eV. It illustrates that the energy match does not depend on the solar radiation and the TE parameters. The effect of the phase change material has also been considered. The melting temperature, mass and heat capacity of the phase change material have been considered in the numerical model. The melting temperature is proved to be important for determining whether it needs to use the phase change material and how much heat should be stored.
