“…Mustafa et al [5] developed a numerical and mathematical model to assess the performance of a photovoltaic thermal nanofluid system. The goal of this work is to theoretically investigate a new PVT system configuration that uses a nanofluid as the working fluid to extract heat from a solar panel and a rectangular stainless-steel tube.…”

The electrical efficiency of the solar cell is effectively increased by the cooling process. In order to create a hybrid collector, the current work addresses how to cool the PV panel using three different nanofluids, including CuO, ZnO, and TiO2. known as a photovoltaic thermal sun collector in numbers (PVT). The volume fraction of the nanoparticles was 0.1, 0.2, and 0.3 vol%. The PV panel was cooled using a copper tube that was attached to the rear of the PV and positioned to cover as much of the back as feasible. To compare them, three distinct flow cross sections (rectangular, square, and circular) were chosen. This numerical analysis was conducted with nanofluid flow rates of 0.5, 1, 1.5, and 2 L/min under solar radiation levels ranging from 450 W/m2 to 750 W/m2. The outcomes demonstrate the PVT system's electrical and thermal efficiency under various circumstances. When nanofluid was added instead of just plain water, the electrical efficiency rose. The cell with CuO/nanofluids had the maximum electrical efficiency at 450 W/m2, which was equal to 11.8%, while ZnO/nanofluids, TiO2/nanofluids, and water had 11.6%, 11.5%, and 10.8%, respectively. The CuO/nanofluids and rectangular sections provided the best value for the highest electrical efficiency of 11.5% and electrical power of 83.17 W.
