Abstract
In the current scenario, in which more and more people are concerned about the degradation of the environment due to the use of polluting energy sources, renewable energies are becoming increasingly important. Among them, the photovoltaic (PV) system has a considerable percentage in energy production. However, as the temperature of the photovoltaic panel increases, its electrical efficiency decreases. Therefore, in an attempt to improve electrical efficiency and increase the useful life of the panels, different cooling methods (active and passive) have been widely studied. Active cooling methods are based on the flow of a working fluid to exchange heat with the surface of the panel. In this sense, nanofluids appear as a working fluid with thermophysical properties that can improve heat transfer processes in this type of application. When active cooling methods are used to remove heat from photovoltaic panels, these systems have the capacity to produce both electrical and thermal energy and they are commonly known as hybrid photovoltaic thermal systems (PV/T). This article reviews and summarizes the main experimental works focus on non-concentrated PV/T systems using nanofluids as working fluids.
