Recent research led by B. Srimanickam from the Department of Mechanical Engineering at Jaya Engineering College in Tamil Nadu has opened new avenues for enhancing the efficiency of photovoltaic thermal (PVT) collectors. Published in the journal ‘Case Studies in Thermal Engineering’, this study explores the use of cerium oxide nano fluids to improve both thermal and electrical outputs of solar panels, addressing a common challenge faced by the solar energy sector.
Solar panels typically convert only a fraction of incoming sunlight into electricity, with much of the energy lost as heat. This heat buildup can significantly hinder the performance of photovoltaic modules. In this innovative study, Srimanickam and his team experimented with PVT collectors using cerium oxide mixed with water as a base fluid. They tested two different flow rates of the nano fluid—0.5 and 1.0 liters per minute (LPM)—to evaluate their impact on energy production.
The results were promising. For the higher flow rate of 1.0 LPM, the electrical efficiency of the PVT collector reached 19.12%, while at 0.5 LPM, it was slightly lower at 18.56%. On the thermal side, efficiencies were recorded at 54.03% and 48.38% for the same flow rates, respectively. “Employing a nano fluid to the receiver might increase the efficiency around 5–10%, compared to utilizing water as a base fluid,” Srimanickam noted, highlighting the significant potential of this technology.
The research indicates that the thermal conductivity of cerium oxide nano fluids is superior to that of conventional cooling mediums like air and water. This improvement could be a game-changer for solar energy systems, which often struggle with overheating and efficiency losses. By integrating such advanced materials into solar technology, manufacturers and energy providers could enhance the performance of solar installations, making them more viable and competitive in the energy market.
The commercial implications of this research are substantial. As the demand for renewable energy solutions continues to grow, innovations that boost the efficiency of solar panels can lead to reduced costs and increased adoption rates. This could ultimately result in a more sustainable energy landscape, with solar power playing a critical role in meeting global energy needs.
