“…In the using of finned PCM, PV-temperature reduction values mostly range between 5 and 20 °C, while max. value is about 26.6 °C obtained by Qasim et al (2020) who used RT27 having Tm = 26.6 °C, very close to the ideal PV temperature of 25 °C where PV module performs at its best. Effect of fin insertion inside PCM reduced PV-surface temperature due to the fact that presence of fins increased conduction heat transfer rate within PCM, which is very much required as thermal conductivity of PCM is very low.…”

“…A reduction of 11.3 °C and 22 °C in PV temperature was reported for cases 2 and 3, respectively, along with an enhancement of 4.25% and 6.48% in the electrical performance. Qasim et al (2020) investigated the performance enhancement of PV systems through extensive experiments using two approaches, i.e., incorporating finned PCM with PV with using a different number of fins and using two PCMs having various melting temperatures, disjointed by finned plate. The usage of 2-fin, 5-fin, 8-fin, and 11-fin assisted in lowering the maximum PV temperature by 23.8 °C, 24.2 °C, 25.1 °C, and 26.6 °C, enhancing the electrical efficiency from 10.1 to 11.2%, 11.7%, 11.9%, and 12.1% respectively.…”

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 the current study, using a composite of aluminum foam matrix impregnated with PCM as a passive cooling technique accelerated the melting time of PCM by about 90 min, which was around 37.5% faster than the pure PCM, indicating an effective performance of the current porous foam. In terms of PV-temperature reduction, the proposed cooling technique provides more than a 15 o C drop in the PV temperature, indicating a competitive performance as a passive cooling technique compared to the other studies such as (Kumar et al, 2020;Qasim et al, 2020). Also, in the current study, it was found that the average PV electrical e ciency was enhanced by 14%, which is higher than most of the improvement percentages obtained by the other systems, as indicated in Table 4.…”

In the present work, a passive cooling strategy combining an aluminium foam matrix (AFM) with PCM was employed to regulate the temperature of a photovoltaic (PV) system The comparison between three PV modules was established ,the first one was conventional without any changes ,the second one was PV combined with PCM (PV-PCM) and the last one was PV combined with modified PCM which contain an aluminum foam matrix embedded in it (PV-PCM/AFM).Outdoor experiments were carried out in the hot weather of Benha, Egypt, which is situated at latitude 30.466° North and longitude 31.185° East. A comparison of the three PV designs was given and analysed, based on PV surface temperature, PCM temperature, open-circuit voltage, output power generated, and electrical efficiency. It was observed that using composite PCM resulted in better heat absorption from the PV module and better temperature distribution inside the PCM enclosure. Furthermore, the results indicated that against the unmodified PV system, the average cell’s temperature in the PV-PCM system was dropped by 13.3% and its electrical power was enhanced by 9%. Meanwhile, the average cell temperature in the PV-PCM/AFM configuration was reduced by 21.6% while the enhancement of the electrical power was at 14%. Furthermore, the findings demonstrated that, as compared to unmodified PCM, AFM impregnation accelerated the melting of modified PCM by roughly 37%.

“…Qasim investigated the effects of fins number on the performance of a PV-PCM through outdoor experimental tests and compared with a reference PV system. 17 PV cell temperature experienced a maximum reduction of 26.5 C with inserting 11 fins on the backside of a 30 W panel, while it was 22.9 C for without-fin configuration. A similar indoor experiment demonstrated that the electrical efficiency of PV-PCM was improved by 5.16% and 6.59% for PV-PCM and PV-finned PCM, 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.
