“…Evidently, the addition of nanoparticles reduces the latent heat of fusion, as the addition of nanoparticles diminished the amount of acid-PCM in the total mixture. These findings are consistent with those of Li et al [14] and Stejskalová et al [15]. Table 2 displays the thermal conductivities of these nc-PCMs.…”

The phase change materials (PCM) based cooling system have gained recent popularity with PV module temperature (TPV) reduction. PCM is an effective thermal energy storage material with the activation of latent heat capacity. Its low heat conductivity has been discovered in several studies. In this study, PCM is chosen to mix with nanoparticles to enhance its thermal conductivity and performance. For an ambient temperature of 38, it is suggested that the melting temperature (Tmelt) of PCM should be between 41 and 44 °C. Nanoparticle composited PCM (nc-PCM) are generated by mixing lauric acid (LA) with three different types of nanoparticles, including aluminum oxide (Al2O3), copper oxide (CuO), and magnesium oxide (MgO) in the following proportions: 100:0, 99:1, 98:2, 94:6, 92:8 and 90:10. It has been shown that the melting points (Tmelt) of the studied nc-PCMs are between 41.18 and 42.47 °C and thermal conductivity increases. According to the findings, the best balance between latent heat of fusion and thermal conductivity should be at 6% nanoparticle. Finally, it is expected that employing these three nc-PCM to reduce the PV module's temperature will enhance PV efficiency.

“…Consequently, in this paper, thermal efficiency at Re = 5500 is the highest value (42.03%) due to the mass flowrate at Re = 5500 being higher than other Re. The overall efficiency is determined by combining the electrical efficiency and the thermal efficiency, as shown in Equation (7). The results indicate that there is no substantial variation in the electrical efficiency for each Re value.…”

“…By incorporating a metal characterized by high thermal conductivity into a PCM, it is possible to augment heat dissipation capacities. Despite increasing the cooling effect and heat transfer properties, the incorporation of thermal additives into a system, results in a reduction in the latent heat of fusion and an increase in the total weight [7,8]. In addition, a number of intriguing studies have been conducted to enhance the reduction in temperature of PV modules.…”

The photovoltaic thermal (PV/T) hybrid system has attracted significant interest from researchers in the solar field. These systems efficiently harness solar radiation, converting it into a usable source of energy and making use of any excess heat generated in the panel. In this study, PCM is utilized as a medium for combining with nanoparticles. Nanoparticle composited phase change materials (nc-PCMs) are created by mixing lauric acid (LA) with magnesium oxide (MgO) and containing them in a micro-channel container to enhance their thermal conductivity. The testing conducted on the water at various dimensionless Reynolds number (Re) of 1100, 2200, 3300, 4400, and 5500. Research studies have discovered that the presence of a water inlet reduces the temperature of the PV module, resulting in an enhancement of the overall efficiency. According to the results, it has been concluded that the best Re for a water system is Re = 5500. The enhanced photovoltaic (PV) modules boosted the electrical efficiency by 16.01% compared to the reference module, leading to an overall efficiency of 54.91%.
