Abstract
Increasing temperature of cell’s surface considers one of the most parameters that affected the performance of Photovoltaic thermal collector (PV/T).A numerical study aid by Ansys Fluent was employed in this study to invesitgate the performance of PV solar cell energy analysis under the same climatic condition of Sherqat-Iraq. A validated CFD model was used in this investigation. It was included six cases four concentrations of (Fe3O4/water) nanofluid, one employed pure water and one used non-cooling PV. The collector of PV/T contains an absorber plate made of Aluminium and serpentine pipe made of copper. The system worked under laminar regime at a constant flow rate (0.0075kg/sec). The results showed that the using of nanofluid as coolant increasing the overall efficiency of PV compared with the water-cooling and non-cooling PV solar cell. It was concluded that the highest thermal and electrical effeciencies are 19.5% and 55.45% respectively when using 1% volume fraction of nanofluid.
