“…It was observed that the PCM maintained the temperature of the PV cell below 85 °C for all months of a year. In a building-integrated concentrated photovoltaic system combined with a PCM heat sink, the temperature of the system was regulated below 78 °C with passive cooling while the temperature was under 43 °C in active cooling with uniform distribution at 5 suns concentration [17]. The thermal performance of a CPV employing PCM laden with graphene nanoplatelets depicted a 7% and 6% increase in power output and efficiency respectively for 0.5% volume concentration of n-PCM at CR=5 [18].…”

In this work, a validated finite element-based coupled optical, thermal, and electrical model is used to assess the performance of a dual concentrated photovoltaic system thermally regulated using a phase change material for the environmental conditions of Lahore, Pakistan. Thermal management of the system is achieved using a selected PCM; that has a melting temperature of 53-56?C, a thermal conductivity of 19 W/m K, and heat of fusion of 220 kJ/kg. Thermal regulation and power output of the system are analyzed for a clear day of six months of a year. It is found that the maximum temperature of the upper photovoltaic cell is ~80?C while for the bottom photovoltaic cell is ~82?C in July. The percentage power gain obtained after the addition of an upper concentrated photovoltaic cell is ~17.9 %. The maximum and minimum power of the system is found to be 0.079 kWh/day/m 2and 0.041 kWh/day/m2 in May and November respectively.

A novel passive cooling heat sink for thermal regulation of concentrated photovoltaics (CPV) and its performance improvement based on phase change material (PCM) embedded in the metal foam has been introduced in this study. Eighteen different patterns have been considered for the heat sink to investigate the influence of series/parallel porosity gradient arrangement, foam material gradient, inclination angle, and pore density. A computational fluid dynamics simulation has been developed to analyze the transient heat charging mechanism and evaluate the effects of porosity/material gradient with different arrangements on the conduction/convection heat transfer processes in the foam-PCM-CPV. The results revealed that parallel positive porosity gradient in y-direction could enhance the natural convection and the conduction heat transfer compared to the series negative porosity gradient in the xdirection and reduce the time-average CPV temperature by 6.76 C and enhance the time-average electrical efficiency by 3.93%. The results also indicated that using an obtuse inclination angle instead of anacute one may reduce the CPV temperature by about 5 C and leads to an electrical efficiency improvement of 2.65%. The lower value of pore density is another determinative factor that could enhance the total absorbed heat by about 12% for different patterns.
