EXPERIMENTAL STUDY ON CONVECTIVE HEAT TRANSFER USING FINS FOR COOLING PV CELLS

Abstract

Experimental research on the impact of fin cooling on silicon solar cell performance metrics was performed, and it was compared to two other cells, one cooled with water and the other without cooling. Photovoltaic (PV) cell waste heat is dispersed, using aluminum fins. The tests were conducted out at a variety of ambient temperatures and with varying levels of illumination. Three test panel were used, the first one used a freestanding photovoltaic system module as a model. The second has a water-cooling system as well, where the water passes through a serpentine heat exchanger, and the third has a fin cooling system, in which water passes through a rectangular helical heat exchanger and fins put on It is equipped with a water-cooling system. as well, although the water passes through a serpentine heat exchanger. Figures (1) and (2) (Serpentine and rectangular helical with fins). The suggested cooling technique significantly increases the produced power and the photovoltaic cell's electric efficiency (helical form) via fins, according to experimental data. At 6 LPM, power climbed to 76.85W and efficiency increased to 9.97%, a performance gain of 38.7% above the uncooled panel.
