Simulation Of Air Flow And Heat Transfer Through Configuration Modified Fins Of Heat Sinks For Photovoltaic Solar Cell Cooling

The photovoltaic(PV)solar cells are of the promising renewable energy to produce electricity.They convert light into electricity through semi-conductive material and are made out of silicone which is abundant on earth,making them non-exhaustible source.Due to sunlight absorption,the PV panels are susceptible to rise the temperature at solar cells what contribute to decrease the electrical conversion [efficiency] by heat generation.Recent researches tend to address this by attaching supporting structures that helps to control the temperature at PV panel.The present research focus on reducing of the PV temperature by altering the three configurations ways of the cooling air-duct of a monocrystalline photovoltaic(PV)cell.The spacing within the fins,the fin’s thickness,and the height of fins were examined to find out which is the best system configuration capable to decrease the PV cell temperature and thus,increase its efficiency.Economical approach was used to unbalance the decision where there’s no much difference in terms of the achieved efficiency.Lastly,models to predict the PV panel temperature were investigated and presented to provide a basic understanding of the change magnitude produced by these three configurations.Highlights are that increasing fins’ height contribute do decrease the solar panel’s temperature in 6.36% of its initial value.Changing fins’ thickness does not contribute greatly to decrease PV cell temperature(about 2.1%)and thus,the electrical efficiency is less dependent its variation.The installation of the air duct increases the cell efficiency.The forced convection is 5% more efficient than natural convection.
