Influence of varying the Ethylene-Vinyl Acetate layer thicknesses on the performance of a polycrystalline silicon solar cell integrated with a microchannel heat sink

Analysis of Thermomechanical Stresses of a Photovoltaic Panel Using a Passive System of Cooling

“…Firstly, the room temperature began at 28 • C and the temperature was increased by 10 • C until it reached 40 • C. The top surface was subjected to a direct solar radiation of 1000 W/m 2 , similar to the analysis carried out by [7,20,21] when the panel was exposed to a theorical film coefficient of 20 W/m 2 • C. In the first step, a steady state thermal analysis was carried out. Its purpose was to simulate the operating temperature condition before the fins were added and with different thicknesses of EVA in order to improve the heat transfer as performed in the study carried out by El-Moneim et al [22]. After this, different types of designs of fins were tested.…”

Development of a new vacuum-based photovoltaic/thermal collector, and its thermal and exergy analyses

“…Published on 19 Recent advancements led to modify the structure of the PV/T system for improving the overall performance. Hassani et al [15] theoretically evaluated the life cycle exergy of PV/T for three different system configurations.…”

“…This thermal absorber is used to regulate the module temperature using pure water as a circulating fluid. The PV module contains glass layer, top EVA layer, silicon wafer, bottom EVA layer and finally a TPT layer with thicknesses of 3mm, 0.5mm, 0.2mm, 0.5mm, and 0.3mm, respectively [19]. The silicon layer generates electricity and it is surrounded by transparent EVA layer to protect it and accomplish electrical insulation [20].…”

“…The silicon layer generates electricity and it is surrounded by transparent EVA layer to protect it and accomplish electrical insulation [20]. The EVA and TPT layers have thermal conductivities of 0.311 W/mK and 0.15 W/mK, respectively which cause significant decrease in the heat transfer to the water in the thermal absorber [19]. Besides, it results in a higher PV cell temperature and lower heat gain and high thermal energy loss compared to other systems.…”

“…This enhances the conduction heat transfer through the EVA layer underneath the silicon wafer without affecting the light characteristics and the electrical insulation characteristics. The second method is decreasing the thickness of this layer from 0.5 mm to 0.2mm [19]. The later thickness is commercially available in the markets for this application and cost-effective compared to the larger thickness.…”
