“…As the IEA reported, solar technologies are projected to experience significant growth over the coming years (Guno et al, 2021). This upsurge is expected to account for over 60% increase globally, leading to a transformation in the production and consumption of electricity (Bisengimana et al, 2023). Solar energy technologies offer an anticipated lifespan of 20 to 30 years (Ibrahim et al, 2011).…”

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.

“…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%.
