“…For this, it needs a continuous source of power which relatively has a large ability to cool the solar cells (Abo-Elfadl et al, 2020b;. The power used in the fan or pump is deducted from the power produced from the cell, reducing the net output power produced from the PV cells (Abdulmunem et al, 2020). This method is divided into two basic types:…”

“…Furthermore, the exergy of the modified system was the highest (around 16.7%). Abdulmunem et al (2020) conducted an experiment for cooling the PV solar cells and used three cells, the first without any additives, the second with PCM only, and the third with PCM and copper foam matrix. The results proved that the electrical efficiency of the third cell increased by 5.68% compared to the first cell, while the efficiency of the second cell increased by 1.97% compared to the first cell.…”

“…Excessive consumption of traditional fossil-based energies at a disturbing rate resulted in an energy crisis and was accountable for accompanying environmental concerns such as global warming, greenhouse harmful gas emissions, and ozone depilation that threaten the security of human beings and the future of the world (Abdulmunem et al, 2020). Therefore, greater demands for clean and renewable energy technologies are raised to reduce our dependency on fossil-based energies and abate its subsequent adverse environmental concerns.…”

Photovoltaic (PV) panels are one of the most important solar energy sources used to convert the sun’s radiation falling on them into electrical power directly. Many factors affect the functioning of photovoltaic panels, including external factors and internal factors. External factors such as wind speed, incident radiation rate, ambient temperature, and dust accumulation on the PV cannot be controlled. The internal factors can be controlled, such as PV surface temperature. Some of the radiation falling on the surface of the PV cell turns into electricity, while the remainder of incident radiation is absorbed inside the PV cell. This, in turn, elevates its surface temperature. Undesirably, the higher panel temperature, the lower conversion performance, and lesser reliability over the long term occur. Hence, many cooling systems have been designed and investigated, aiming to effectively avoid the excessive temperature rise and enhance their efficiency. Many cooling methods are used to cool solar cells, such as passive cooling, active cooling, cooling with phase change materials (PCMs), and cooling with PCM with other additives such as nanoparticles or porous metal. In this work, the common methods utilized for cooling PV panels are reviewed and analyzed, focusing on the last methods, and summarizing all the researches that dealt with cooling PV solar cells with PCM and porous structures.

“…In active cooling, the use of mechanical devices such as pump or fan blower are necessary to provide a continuous effect on the solar cells. But, it could reducing the net output power produced from PV cells to power the pump and fan [7]. A series of investigations have been performed previously on force air cooling that includes a practical experiment to use a number of DC fans directed at the back of the PV cell [8].…”

Excessive operating temperature of Photovoltaic (PV) panel by high levels of solar irradiation would affect its conversion efficiency, Hence One way of improving the efficiency of photovoltaic system is to maintain a low operating temperature by introducing a passive cooling system. Subsequently, this study investigating the effect on surface temperature reduction and voltage output of PV panel, by introducing the combination of heat pipe and fin as a cooling device. Each set of the cooling devices consisted of two copper heat pipes and two units of heat sinks. Two sets of the cooling devices were installed at the back of the PV panel, and experimental work had been performed at fixed 0 ° horizontally. The experiment was conducted at a constant time under Malaysia’s climate at constant ambient temperature ranging from 33 °C to 34 °C. The temperature of the panel and open-circuit voltage (VOC) was recorded before and after the installation of the cooling system by using Arduino data logger. Four thermocouples for different places and a voltage sensor were installed into the system to enable recording the data of voltage and temperature simultaneously. The results showed 4 o C or 6.6 % surface temperature reduction and 0.29 V or 2.8 % voltage gained respectively when the proposed cooling devices were installed to the PV panel.

“…25 They concluded that foam-PCM boosted the heat transfer from PV cell to working fluid and prevented the fluid temperature drop by discharging the absorbed thermal energy. In another attempt, 26 a metal foam with 98% porosity and a width of 2.5 cm was attached to a PV module and filled with CNT-PCM. Under a constant irradiance of 1000 W/m 2 in the laboratory conditions, module temperature reduction and electrical efficiency by 13.3% and 5.7% were obtained, respectively.…”

A novel passive cooling heat sink for thermal regulation of concentrated photovoltaics (CPV) and its performance improvement based on phase change material (PCM) embedded in the metal foam has been introduced in this study. Eighteen different patterns have been considered for the heat sink to investigate the influence of series/parallel porosity gradient arrangement, foam material gradient, inclination angle, and pore density. A computational fluid dynamics simulation has been developed to analyze the transient heat charging mechanism and evaluate the effects of porosity/material gradient with different arrangements on the conduction/convection heat transfer processes in the foam-PCM-CPV. The results revealed that parallel positive porosity gradient in y-direction could enhance the natural convection and the conduction heat transfer compared to the series negative porosity gradient in the xdirection and reduce the time-average CPV temperature by 6.76 C and enhance the time-average electrical efficiency by 3.93%. The results also indicated that using an obtuse inclination angle instead of anacute one may reduce the CPV temperature by about 5 C and leads to an electrical efficiency improvement of 2.65%. The lower value of pore density is another determinative factor that could enhance the total absorbed heat by about 12% for different patterns.
