As the world shifts towards a more sustainable future, solar energy has emerged as a preeminent and economically feasible alternative to traditional energy sources, gaining widespread adoption. This study presents a reversed circular flow jet impingement (RCFJI) which aims to improve the performance of a bifacial PVT collector. An indoor experiment using a solar simulator to assess the energy, exergy, and economic efficiency of a RCFJI bifacial PVT collector. The study was carried out using a solar irradiance ranging from 500-900W/m2 and a mass flow rate between 0.01-0.14 kg/s. Energy performance-wise, the highest photovoltaic efficiency achieved was 11.38% at solar irradiance of 500 W/m2, while the highest thermal efficiency achieved was 61.4% under 900 W/m2, both obtained at 0.14 kg/s mass flow rate. Regarding exergy performance, the highest photovoltaic exergy obtained was 47.27 W under 900 W/m2 at 0.14 kg/s, while the highest thermal exergy was 9.67 W at 900 W/m2 at 0.01 kg/s. Overall, higher solar irradiance is more desirable for energy and exergy performance. Meanwhile, economic point of view, lower solar irradiance is preferable. Based on the findings, the optimal mass flow rate was 0.06 kg/s.

“…Therefore, to calculate the CBR value, the annual cost (AC), annual energy gain (AEG), and annual exergy gain (AEXG) must be determined. The following equations are developed from previous studies (Ewe et al, 2022;Nazri et al, 2018). Table 2 lists the data information involved in the economic analysis.…”

“…Active cooling methods consume electricity to circulate water, air, or nanofluid over the PV surface, removing the heat generated in the PV module. The active cooling methods are water cooling (Shahverdian et al 2021;Abdul-Ganiyu et al 2021), nanofluid cooling (Jidhesh et al 2021;Wahab et al 2020), liquid immersion or submerging, water impingement (Javidan and Moghadam 2021;Ewe et al 2022), forced air cooling (Ahmad et al 2021;Lamrani et al 2021), microchannel (Ali et al 2021), and thermoelectric cooling Multiphysics. The authors analyzed the effect of PCM fill volume and concentration ratio on the proposed system and compared it with the CPV alone system.…”

Temperature regulation of photovoltaic (PV) modules increases their performance. Among various cooling techniques, phase change materials (PCMs) represent an effective thermal management route, thanks to their large latent heat at constant temperatures. Radiative cooling (RC) is also recently explored as a passive option for PV temperature regulation. In this paper, a heat sink (HS), phase change materials, and radiative cooling are integrated with photovoltaic modules to get low and uniform temperature distribution along the PV module and its improved performance. Eight different combinations are considered for the proposed system, including HS, PCM, and RC and their various combinations. The PCM is selected according to the environmental conditions of a specific location. A comprehensive 2-D model is developed and analyzed in COMSOL-Multiphysics software by solving the governing equations using the finite element method. The performance analysis is carried out for the climatic conditions of the Atacama Desert, having high solar radiation and ambient temperature. The effects of PCM height, ambient temperature, wind velocity, and solar radiation on the performance of the proposed system are studied. The performance of eight different configurations is also compared. The maximum reduction in PV temperature, maximum PV power and a minimum drop in PV conversion efficiency are observed to be 22 K, 152 W and 14% using a combined heat sink and radiative cooling systems, among all other configurations. The findings of this study can be used to select the best PV cooling method among different configurations.

“…Solar energy systems can be categorized into photovoltaic and thermal systems. The combination of these two systems is known as photovoltaic thermal, which enables the collector to harness electrical and thermal energy simultaneously (Ewe et al, 2022;Chen et al, 2022;Bisengimana et al, 2023). The integration of photovoltaic thermal (PVT) systems with additional elements, such as water, wind, and, more recently, phase change material (PCM), has been explored as means to enhance the overall efficiency of the photovoltaic systems (Hamzat et al, 2021;Diwania et al, 2020;Chandrasekar et al, 2021).…”

A relatively new technology, a hybrid photovoltaic thermal (PVT) solar collector, allows for producing electrical and thermal energy. However, the module heats up more when exposed to sunlight thanks to the PVT collector's incorporation, reducing its efficiency. Consequently, lowering the operating temperature is crucial for maximizing the system's effectiveness. This research aims to create a photovoltaic thermal phase change material (PVT-PCM) solar collector and evaluate its energy performance through a controlled laboratory environment. Two different PVT collector designs, one using water and the other using a phase change material (PCM), were evaluated using a spiral flow configuration. Under a sun simulator, the PVT solar collector was subjected to 400 W/m2, 600 W/m2, and 800 W/m2 of solar irradiation at three different mass flow rates. The results showed that under 800 W/m2 of solar irradiation and 0.033 kg/s mass flow rate, the collector using water could only reach an overall maximum efficiency of 64.34 %, whereas the PVT-PCM configuration with spiral flow had the maximum performance, with an overall efficiency of 67.63%.
