“…The PV temperatures at 9am and 2pm were found to be 16°C and 3°C lower than that without porous media. Huo et al [119] have carried out an experimental study to investigate the cooling efficiency of tube plate PV/T systems with iron filings filled. Comparing to that without iron filings filled, the calculated equivalent thermal conductivity of filling iron was 43.91 W/(m•K), with reduced cell temperature by 3.5°C to 6.5°C, leading to increased electrical yield by 19.8%.…”

When converting solar energy to electricity, a big proportion of energy is not converted for electricity but for heating PV cells, resulting in increased cell temperature and reduced electrical efficiency. Many cooling technologies have been developed and used for PV modules to lower cell temperature and boost electric energy yield. However, little crucial review work was proposed to comment cooling technologies for PV modules. Therefore, this paper has provided a thorough review of the up-to-date development of existing cooling technologies for PV modules and given appropriate comments, comparisons and discussions. According to the ways or principles of cooling, existing cooling technologies have been classified as fluid medium cooling (air cooling, water cooling and nanofluids cooling), optimizing structural configuration cooling and phase change materials cooling.Potential influential factors and sub-methods were collected from the review work, and their contributions and impact have been discussed to guide future studies. Although most cooling technologies reviewed in this paper are matured, there are still problems need to be solved, such as the choice of cooling fluid and its usability for specific regions, the fouling accumulation and cleaning of enhanced heat exchangers with complex structures, the balance between cooling cost and net efficiency of PV modules, the cooling of circulating water in tropical areas and the freezing of circulating water in cold areas. To be advocated, due to efficient heat transfer and spectral filter characters, nanofluids can promote the effective matching of solar energy at both spectral and spatial scales to achieve orderly energy utilization.

“…Experimental investigations were carried out at radiation intensity values ranging from 400-800 W/m 2 to improve the conventional structure of the module. The experiments shown that the module experiences a temperature drop of 3.5-6.5 °C, which increases the ηelec by 19.8% compared to the other tube-plate system [16]. In an independent investigation, the PV/T hybrid system designed capable of concurrently producing electricity and hot water.…”

This study investigates the effect of ambient temperature and solar radiation intensity on the performance of the photovoltaic thermal (PV/T) system. As solar radiation intensity and ambient temperature increase, the cell temperature of photovoltaic (PV) panels also increases, causing a corresponding decrease in performance. The PV/T system is specifically designed to enhance the performance of PV panels and energy storage. In this study, water is utilized as a heat transfer fluid to lower the PV panel temperature. To achieve the desired outcome, a closed loop with a tank volume of 25 liters is utilized to circulate water at a constant mass flow rate of 0.0161 kilograms per second. Consequently, the heat that transfers from the panel cells to the heat transfer fluid is accumulated in a 50-liter water tank. The thermal performance of the photovoltaic panel, as well as the photovoltaic thermal system with and without a fan-cooled heat exchanger, were evaluated. As a result, the electrical performance of the photovoltaic/thermal system increases by 2%. In PV/T systems designed for maximum efficiency, the presence of a fan-cooled heat exchanger leads to a 13% reduction in thermal performance. Furthermore, the temperature of the water contained within the tank experiences a 50% increase.

Combining phase change material with a hybrid photovoltaic thermal system can be a reasonable solution for excessive temperature distributions and inadequate heat control in traditional photovoltaic thermal modules. This work proposes a mathematical model to assess the transient processes of a hybrid photovoltaic thermal solar system with phase change materials in comparison to a conventional photovoltaic panel. The studied hybrid module is composed of (the cover glass, photovoltaic plate, absorber plate, phase transition materials layer, and water in the tubing). The employed system parameters were selected on an energy-saving basis in the different system layers. The differential equations determining energy exchange between the different parts in both systems were numerically solved using the Finite Difference Method applied to MATLAB software. The transient model's validity is first tested by comparing the prediction temperatures of each layer of the photovoltaic thermal system with those numerical and experimental studies in literature in which the maximum discrepancy is less than 1.5°C. Then, the results of the transient model are investigated in real outdoor weather conditions using meteorological data. The results illustrated that the hybrid module diminishes the temperature of the photovoltaic layer by roughly 21.9°C compared to the standalone photovoltaic panel, leading to a 1.95 % enhancement in electrical performance.
