“…Thus, the selection of nanofluid type in a PVT system is vital to ensure compatibility and meet the desired performance criteria. Table 6 summarizes studies involving PVT systems with nanofluids as coolant media, featuring different types and configurations [54,[137][138][139][140][141][142][143][144][145][146][147].…”

“…The maximum thermal efficiency occurred at a 0.75% volume concentration of MgO nanofluid, with higher concentrations leading to diminished efficiency gains. Adun et al [141] advanced nanofluid technology in PVT systems by combining three types of nanoparticles (Al 2 O 3 -ZnO-Fe 3 O 4 ) in mixture ratios of 1:1:1 and 2:1:1, without using surfactants. The highest thermal conductivity was achieved at a mixture ratio of 2:1:1 across all temperatures.…”

With the growing demand for photovoltaic (PV) systems as a source of energy generation that produces no greenhouse gas emissions, effective strategies are needed to address the inherent inefficiencies of PV systems. These systems typically absorb only approximately 15% of solar energy and experience performance degradation due to temperature increases during operation. To address these issues, PV–thermal (PVT) technology, which combines PV with a thermal absorber to dissipate excess heat and convert it into additional thermal energy, is being rapidly developed. This review presents an overview of various PVT technologies designed to prevent overheating in operational systems and to enhance heat transfer from the solar cells to the absorber. The methods explored include innovative absorber designs that focus on increasing the heat transfer contact surface, using mini/microchannels for improved heat transfer contiguity, and substituting traditional metal materials with polymers to reduce construction costs while utilizing polymer flexibility. The review also discusses incorporating phase change materials for latent heat absorption and using nanofluids as coolant mediums, which offer higher thermal conductivity than pure water. This review highlights significant observations and challenges associated with absorber design, mini/microchannels, polymer materials, phase change materials, and nanofluids in terms of PV waste heat dissipation. It includes a summary of relevant numerical and experimental studies to facilitate comparisons of each development approach.

“…Compared with a PV system that uses water instead of an improved cooling system, utilization of nanofluid with 4% wt concentration and turbulent flow can create a 50% and 30% increment in system exergy efficiency, respectively. Adun et al [59] analyzed a PV/T system utilizing a ternary nanofluid, Al 2 O 3 -ZnO-Fe 3 O 4 /water, and found that the mixture ratio of the particle influences the system performance. Furthermore, the exergy analysis revealed that solar irradiance pattern is observed in the system total exergy efficiency.…”

Solar Photovoltaic (PV) systems are degraded in terms of efficiency by increment in their temperature. To keep away from efficiency degradation regarding the temperature increase, various thermal management techniques have been introduced to keep the temperature low. Besides improvement in electrical efficiency, the overall efficiency can be enhanced by using the extracted thermal energy from the cell. The extracted heat in these systems, known as PV/Thermal (PV/T), can be applied for some purposes including water or air heating. This article reviews the works on the PV/T systems exergy analysis and discusses their findings. Based on the findings of the reviewed works, different factors such as the system configuration, used components and elements, and working conditions affect the exergy efficiency of these systems. As an example, use of coolants with improved thermal features, i.e., nanofluids, can cause improvement in the exergy efficiency. In addition to the nanofluid, making use of the thermal energy storage unit can further enhance the exergy efficiency. Furthermore, it has been observed that the materials of nanostructures can be another element that influences the enhancement of exergy efficiency. Moreover, the usage of some components such as glazing can lead to avoidance of thermal energy loss that would be beneficial from an exergy point of view. Finally, according to the reviewed works and knowledge of the authors, some suggestions are represented for future works in this field.

“…Literature shows that PVT technology's efficiency increased by roughly 4% when ternary/hybrid nanofluid was used [ 24 ]. Adun et al [ 25 ] assessed various effects of a PVT system employing a novel water-based Al 2 O 3 –ZnO–FeO 4 ternary nanofluid. The maximum and total exergy efficiencies of PVT were determined to be 1.53% and 14.77%, respectively.…”
