Solar cell cooling system

Various cooling techniques can be employed to cool solar cells, including passive cooling methods, such as natural convection and radiation, and active cooling methods, involving the use of a water-spray cooling technique (Figure 4) . Figure 5 shows the immersion of polycrystalline solar cells in water .

Cooling cells and coordinating their use are vital to energy efficiency and longevity, which can help save energy, reduce energy costs, and achieve global emission targets. The primary objective of this review is to provide a thorough and comparative analysis of recent developments in solar cell cooling.

Active PCMs offer precise control, while passive PCMs are simpler and more efficient in terms of energy use, but they offer less control over temperature. Moreover, an innovative review of advanced cooling methods is presented, highlighting their potential to improve the efficiency of solar cells. 1. Introduction

The cooling system helps maintain optimal temperatures, thereby enhancing the efficiency and lifespan of the PV panels . Additionally, another important factor affecting the productivity of solar panels is dust accumulation on their surfaces, which can significantly reduce light transmission.

In regions with more moderate temperatures, the use of a simple finned heat sink is effective in cooling photovoltaic cells. However, it is important to note that this approach adds additional weight to the panels. Another approach, known as forced convection, is effective in cooling, although it demands considerable fan power.
