This study addresses the thermal stress issues caused by conventional cooling methods on photovoltaic (PV) cells, which reduce their efficiency and lifespan. Recently, the water-based spectral splitting filter (SSF) system was introduced as a solution to optimize solar energy conversion. The research fills a significant gap by focusing on the practical application of water-based SSFs under actual high-temperature conditions in Cairo (latitude of 30.1°N). The study evaluates the effects of radiation intensity (200–1000 W/m2), optical fluid flow rate (0.001–0.01 kg/s), and filter thickness (2–10 mm) on the system's performance. According to the data, the SSF system is a superior cooling technique as it can lower the PV temperature by 93% over a range of radiation intensities. The system's performance is also found to be positively influenced by increasing the SSF's thickness and flow rate, achieving 15% and 29.4% maximum increases in the fill factor and electrical efficiency, respectively, over the conventional PV panel at a thickness of 10 mm and a flow rate of 0.01 kg/s. Additionally, experimental data support the modeling findings, with a maximum variation of ±4.7% in the efficiency of the PV panel.

AbstractDue to the scarcity of freshwater resources in many arid regions of the world, as well as rapidly growing populations and industrialization, various desalination technologies have been developed and enhanced to improve the performance of saline water purification with high quality. Integrating solar energy technologies with desalination systems would alleviate the running out of fossil fuel sources, reduce costs, and improve energy efficiency. Solar‐powered desalination systems could be a viable and efficient method for treating highly saline water for human consumption. Obtaining reliable and accurate design parameters for such hybrid systems plays a significant role in determining the system performance of solar‐driven desalination systems. The present review provides a comprehensive review of various solar‐driven membrane‐based desalination systems to investigate the impact of design and operation parameters for solar and desalination units on the effectiveness of the hybrid solar/desalination system. Recent advancements in utilizing numerous solar energy sources for desalination are analyzed herein. The economic implications of various membrane desalination operations for different solar energy sources are also discussed. It was revealed that the solar system design parameters, desalination unit characteristics, feed water properties, and climate conditions all affect the functionality and productivity of the membrane‐based solar‐powered desalination system. The feed pressure, number and shape of membranes, and the integrated solar system, all have significant impacts on the performance of the hybrid system. This article provides a pathway for desalination researchers to select the optimal design and operation parameters for hybrid solar‐powered membrane‐based desalination systems. Notably, they are found more feasible and sustainable than traditional desalination processes. Several related conclusions and future perspectives are reported herein.This article is categorized under: Sustainable Energy > Solar Energy

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.

The present work investigates the effect of the nanoparticles concentration on the optical and stability performance of a water‐based nanofluid in solar photovoltaic/thermal (PV/T) systems experimentally and numerically. A novel nanofluid is formulated with the inclusion of the reduced graphene oxide decorated with silver (rGO‐Ag) nanoparticles in water. Five different concentrations of nanoparticles in the range from 0.0005 to 0.05 wt% is suspended in water to prepare the samples. Optical properties are measured using UV‐Vis. The UV‐Vis absorption analysis reveals that all samples show consistent optical absorption coefficient (α) at higher value (more than 3 cm−1) in the range of 1.5 to 4 eV. The application of optical filtration (OF) using water/rGO‐Ag nanofluid in hybrid PV/T system presented more solar energy absorption through the OF. The hybrid system shows better performance at concentrations less than 0.0235 wt% compared to the PV system without integration with optical filtration. The hybrid solar PV/T system with OF using water/rGO‐Ag nanofluid is able to produce thermal energy with efficiencies between 24% and 30%.
