“…The tube-plate structure can be categorized into several types, such as oscillatory, spiral, serpentine, reticulate, and parallel tubular architectures. Arslan et al [25] conducted a study on the flow rate variations of a PVT fan with a tube-plate structure. They designed and tested a new type of copper fin air-cooled PVT, varying the voltage (6, 8, 10, 12 V) to control the fan's flow rate.…”

Photovoltaic–thermal (PVT) technology is gaining popularity due to the diminishing availability of traditional fossil fuels and escalating environmental concerns. Enhancing the heat dissipation of PVT to improve its electrical and thermal performance remains a significant task. This study simulates the thermodynamic and heat transfer characteristics in multiple novel PVT structures by examining the impact of various factors such as collector materials, radiation intensity, mass flow rate, and inlet temperature. This work also identifies the optimal mass flow rate for locations with different solar radiation. The numerical results indicate that the electrical efficiency of a designed cylindrical structure has increased by 1.73% while the thermal efficiency has increased by 8.29%. Aluminum is identified as the most cost-effective material for the collector. The optimal mass flow rates in selected locations of Xining, Taiyuan, and Turpan are 0.36 kg/s, 0.35 kg/s, and 0.30 kg/s, respectively. The numerical results provide valuable insight into optimizing the design and operating conditions of PVT systems.

“…The following are some of the research studies that have focused on enhancing the photovoltaic modules' performance by means of active cooling techniques. Arslan et al 10 conducted a numerical and experimental analysis to design a new type of air‐cooled PV/T solar collector with copper fins and tested it with variable air flows. They are interested in designing a fin with a growing number of holes and an increasing height from the inlet to the system outlet.…”

Solar panels' efficiency is highly affected by high‐operating temperatures, especially in semi‐arid and arid regions. This outdoor experimental study aimed to enhance the energy performance of the photovoltaic module by integrating two fans at the outlet of the thermal/photovoltaic hybrid system to ensure forced ventilation. The work novelty depending on achieving low energy consumption by DC fans, so that there is a proportional relationship between the intensity of solar radiation and the energy produced and consumed. The influence of the reduced temperature, operating temperature, and solar radiation intensity on the energy performance of the photovoltaic/thermal hybrid system was analyzed experimentally. The obtained results showed an improvement in electrical and overall efficiency of the new hybrid system by about 4% and 60%, respectively, compared to the conventional photovoltaic module. On the contrary, a decrease in the temperature of the PV module installed in the hybrid system was measured by about 9°C, compared to the conventional photovoltaic module. In addition to the effectiveness of the new technology air cooling proposed at the lowest consumption cost, the thermal energy generated from the proposed system can be invested in solar drying and building applications.
