A review: The development of crucial solar systems and corresponding cooling technologies

Solar energy is considered the most promising form of renewable energy due to its abundant reserves, widespread availability, and minimal environmental impact. However, the traditional PV (Photovoltaic) systems cannot achieve high electrical efficiency because of the technical restrictions of solar cells and high maintenance costs also hinder the large-scale popularization of PV system. The appearance of CPV (Concentrated Photovoltaic) systems solve the above problems, increasing the electrical efficiency to a great extent, but appropriate cooling technologies are of great need to decrease the cell surface temperature under high heat flux density caused by concentrators. This paper provides a comprehensive review of the different photovoltaic systems and corresponding cooling technologies, detailed investigating the distinctions, applicability, development trend and future technologies of both passive and active cooling methods. The analysis will shed light on the advancements made in increasing efficiency of crucial solar systems, as well as the importance of effective cooling techniques to maintain optimal performance in crucial solar systems.
