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.

Photovoltaic technology plays a crucial role in harnessing renewable energy. While photovoltaic panels directly convert solar energy into electricity, more than 50% of solar radiation is lost as waste heat, diminishing the overall efficiency of the panels. This study reviews various cooling technologies for photovoltaic systems, focusing on the use of phase change materials for cooling in photovoltaic systems. Phase change materials, known for their high latent heat capacity, are extensively used in thermal energy storage applications. Incorporating phase change materials in photovoltaic systems can increase thermal storage potential by 30–50% compared to conventional systems, leading to a 70% extension in heat storage duration and various levels of enhanced power output. The main purpose of the article is to review the advantages and disadvantages of various technologies, determine the research direction of phase change materials for cooling systems in photovoltaics, and ensure the reliability of this technology.

“…The solar photovoltaic/thermal (PV/T) system is one of the key research focuses of the solar energy utilization field due to its high thermal energy output and comprehensive utilization compared with PV or solar thermal systems alone [1,2]. It was widely used in several industries, like power generation stations [3][4][5], dryers [6,7], building heating [8,9,10], and desalination systems [11][12][13]. In recent years, great progress has been made in the optimization and application of solar photovoltaic/thermal (PV/T) systems.…”

“…The use of pure water as working fluid improves thermal and electrical yields by 4.5% and 1.85%, respectively, compared to the EG-W mixture. A new type (double pass) of photovoltaic/thermal panel and a novel latent heat storage unit integrated with the condenser of the heat pump were designed and manufactured in Kosan and Aktas' study [8]. The numerical analysis was performed using the Ansys Fluent program to characterize the thermal behavior of the phase change material in the latent heat storage unit.…”

This study presents a theoretical study on the super thin and conductive thermal absorber with built-in corrugated channels on the basis of previous field experiments. The flow and heat transfer characteristics of the corrugated channels are simulated to identify the factors affecting photovoltaic/thermal (PV/T) system efficiency. The influences of the structural parameters such as the corrugation number, the corrugation area, and the flow channel width on the water outlet temperature and heat collection are discussed in order to support the structural optimization design of the hybrid PV/T system. The simulation results were validated to be in good agreement with experimental results. The results indicate that increasing inlet water velocity leads to a decrease in the outlet temperature. It was found that the corrugation area and the flow channel width have impacts on the outlet temperature of the hybrid PV/T collector panel. When the flow channel width of the absorber plate is reduced from 4 mm to 3 mm, the outlet temperature attained is between 298 and 302 K, and the heat collection is in the range of 16.2–51.4 MJ/h. This led to an increase in the amount of heat collected by 18.6%.
