Design and development of novel cooling arrangement for PV cell

The demand for sustainable energy has highlighted the importance of photovoltaic (PV) Cells in power generation. However, polycrystalline PV cell efficiency is hindered by temperature sensitivity. This leads to design a novel cooling system using cooling medium. The cooling system with and without baffles are preferred for experimentation. The ethylene glycol is in demand due to its availability and miscible nature in water at all concentration. The concentration of ethylene glycol is varied from 5%, 10%, 15% and 20% to study the evaporation rate of water. The requirement of water for cooling PV is also studied with and without adding ethylene glycol. With the help of ethylene glycol, the efficiency enhancement without compromising rate of evaporation is achieved. The outcome of the present paper indicates that efficiency of polycrystalline PV Cell is increased by 1.725% using novel cooling system with 20% of ethylene glycol concentration.
