This paper discussed the results of numerical studies of the flow field and heat transfer characteristics for a turbulent slot jet of water on photovoltaic solar cell. A wide range of various flow and geometrical parameters, with jet Reynolds number (Re) in the range of 10000-30000, and jet-to-photovoltaic distance (h) and the nozzle diameter have been considered. The results have been presented in terms of the average Nusselt numbers, and the heat transfer coefficients. The results show a significant improvement of heat transfer due to the jet impingement of water for cooling photovoltaic solar cell. An increase in the jet Reynolds number leads to an improved average Nusselt numbers increases as the nozzle-to-photovoltaic spacing decreases.
