“…In Alexandria, Egypt, a new, simplified one-dimensional mathematical model was developed by Elsheniti et al [82] to predict the temperature of a PCM in contact with PV cells, with near-computational fluid dynamics (CFD) accuracy while greatly reducing calculations and time, based on estimation of the thermal conductivity equation enhanced by thermal currents within the PCM during the melting and solidification processes. A CFD model was also developed to simulate PV/PCM performance.…”

The target of the current study was to review and analyze the research activities of previous studies on cooling techniques for thermal photovoltaic (PV) systems using phase-change materials. These materials have the ability to absorb and release certain amounts of potential heat energy by changing their state from phase to phase (solid–liquid) within a small temperature range. These materials have been used to regulate and lower the temperature, increase the efficiency, and extend the life of solar cells. A host of improvements have been made to phase-changing materials through the combined utilization of phase-change materials and fins in addition to nanoscale fluids to enhance electrical efficiency. When using PCMs, the thermal, electrical, and overall efficiency improved by 26.87%, 17.33%, and 40.59%, respectively. The addition of nanomaterials increased phase-change materials’ specific heat capacity and thermal conductivity, thus reducing the plate temperature and increasing the electrical efficiency. It was found that using of nanoparticles together with a microcapsule had better performance in terms of energy efficiency. Studies indicated that variable phase materials were not used because of their high cost and lack of stable operational design. Therefore, the effect of phase-change materials on PV/thermal (PVT) system performance needs further investigation and study.

“…Karthick et al (2018) established an experimental room with a building integrated PV-PCM system and evaluated its 10% improved conversion efficiency with respect to the reference PV system [ 32 ]. In recent study of PV-PCM system, Elsheniti et al (2020) proposed a simplified model to predict conduction behavior of PCM with significantly high accuracy but short computational time compared with CFD model [ 33 ]. As a result, efficiency improvement of PV-PCM system according to different PCM thickness was derived, which indicated that to maximize performance of the system, using appropriate PCM thickness is critical.…”

“…It was stated that the electrical efficiency of PV-PCM and PV/T nanofluid systems was increased by 15-23% and 20%-37%, respectively. Elsheniti et al (Elsheniti et al, 2020) analyzed the temperature distribution of PV-PCM systems with CFD and a new approach "1D Enhanced Conduction Model (ECM)". In addition, electrical efficiencies of PV systems with and without PCM at different slope angles of each season in Alexandria, Egypt were obtained.…”

An experimental study was carried out to examine the efficiency of solar energy in photovoltaic thermal collectors (PV/T) with energy storage. A photovoltaic thermal collector was used to generate both electrical energy and hot water. The effects of inclination angle of PV/T collectors on power, temperature, energy and exergy values were investigated. Also, effects of cellular shading are tested and discussed. PV/T was compared with the conventional PV/T collector by adding phase change material (PCM) for one of the collectors. In addition, the effect of different shading conditions (small, medium and large circle) on the power and hot water output of the PV/T collector at optimum slope angle were investigated. It is found that 7 ºC temperature differences are
