Thermal and structure analyses of high concentrator solar cell under confined jet impingement cooling

摘要: Abstract The high solar light concentration onto the photovoltaic cell leads to extremely temperature, which significantly decreases efficiency and degrades its lifetime due thermal stresses. One of main challenges these types cells is propose an efficient cooling technique that allows operate under recommended operating conditions. Therefore, focus this study was develop a comprehensive three-dimensional model for concentrator photovoltaic/thermal (HCPV/T) system. This comprises triple-junction integrated with thermo-fluid four distinct designs confined jet impingement heat sinks. results showed electrical increased coolant flow rate, sufficient temperature uniformity can be achieved by configurations. Additionally, use configurations consumed slight pumping power less than 1% generated in cell. maximum local uncooled predicted reach 1360 °C ratio 1000 Suns. Under same conditions, single design reduced about 65 °C mass rate 50 g/min. It should noted stress substantially decreased increasing rate. Exergetic analysis attained total exergy 53.25% at 25 g/min.
