“…Significant improvements can be achieved in the melting rate, energy density, and power density of composite PCM by modifying the porosity of composite metal foam. In another paper, Li et al [ 79 ] once again established the pore‐scale lattice Boltzmann model, using X‐ray microcomputed tomography to characterize the complex microstructure of metal foam and calculate the dynamic temperature and flow fields in common scenarios.…”

Photovoltaic (PV) cells convert solar energy into electricity is currently the cleanest and most economical way to generate electricity. Nevertheless, just a portion of the solar power can be transformed into electrical energy, while the remaining portion is converted into heat, leading to an increase in the temperature of the PV cells. The rise in temperature will not only cause a decrease in the electrical efficiency of PV cells, but it may also impact their lifespan. By placing phase change materials (PCMs) on the back of the PV cells, it is possible to decrease the temperature increase and enhance the electrical efficiency. The heat collected by PCMs can also be taken away using liquid cooling and put to use. In this paper, the classification, performance evaluation and composite modification technology of PCMs are introduced in detail. The practical application requirements of PCMs in thermal management of PV cells are discussed, and some new ideas of applying PCMs to PV cells are prospected. Moreover, the prior investigations regarding the incorporation of PCMs with PV systems and PV/T systems have also been compiled, encompassing the various research perspectives and methodologies employed. In addition, the possible development direction in the future is prospected.This article is protected by copyright. All rights reserved.

“…K PCM is the second essential parameter in cooling the PV module. To enhance the cooling effect, it is necessary to increase the K PCM unless the conduction barrier reduces the heat transfer rate between the PV module and PCM [128][129][130]. Several researchers claim that incorporating a thermal distribution heat sink inside the PCM container helps transfer the thermal energy from the PV module to the PCM's inner surface [93,94,104].…”

Several studies have concentrated on cooling the PV module temperature (TPV) to enhance the system’s electrical output power and efficiency in recent years. In this review study, PCM-based cooling techniques are reviewed majorly classified into three techniques: (i) incorporating raw/pure PCM behind the PV module is one of the most straightforward techniques; (ii) thermal additives such as inter-fin, nano-compound, expanded graphite (EG), and others are infused in PCM to enhance the heat transfer rate between PV module and PCM; and (iii) thermal collectors that are placed behind the PV module or inside the PCM container to minimize the PCM usage. Advantageously, these techniques favor reusing the waste heat from the PV module. Further, in this study, PCM thermophysical properties are straightforwardly discussed. It is found that the PCM melting temperature (Tmelt) and thermal conductivity (KPCM) become the major concerns in cooling the PV module. Based on the literature review, experimentally proven PV-PCM temperatures are analyzed over a year for UAE and Islamabad locations using typical meteorological year (TMY) data from the National Renewable Energy Laboratory (NREL) data source in 1 h frequency.
