A Review on Using Nanofluids as Coolant of Photovoltaic Panelsto Enhance their Electricity Generation

Nowadays suppling electrical energy has become a critical issue for many countries. Moreover, the use of conventional onessuch as combustion of fossil fuels is not recommended, since they are harmful for the environment. So, the world is movingtoward renewable and green energies. Photovoltaic (PV) power plant is one of the best ways. But this technology has some weakpoints. In this paper, the inverse dependency of the PV cell temperature with their electrical efficiency was considered. Fromdifferent cooling methods, the circulation of nanofluids as coolant, is reviewed here. So, different enhancement methods whichleads to increase in the performance of circulating nanofluid were considered and discussed. To have a better sight for the readers,the actual or schematic view of the experimental setups, were added to the text, too.
