A comprehensive review on integration of receiver geometries, nanofluids, and efficient thermal energy storage for solar parabolic dish collectors

Solar energy has received substantial attention as a source of clean and sustainable power. Among various techniques, solar parabolic dish collectors (PDCs) show significant promise in effectively harnessing solar energy. However, maximizing their thermal efficiency requires overcoming challenges like heat loss and solar intermittency. This review article critically analyzes recent advancements in PDC technology, particularly those focused on improving thermal performance. Specifically, we have explored advancements in receiver geometries, integration of thermal energy storage, and the utilization of nanofluids as heat transfer fluids (HTFs). Our review method involves examining the effectiveness of various receiver geometries, from traditional designs to creative new configurations, within PDC systems. Furthermore, the paper investigates the potential of employing nanofluids as HTFs in different receiver geometries to enhance the overall thermal performance. As a novel contribution, we propose the synergistic integration of optimized receiver geometries, nanofluids, and phase change materials for thermal energy storage within PDCs. This innovative approach has the potential to revolutionize PDC technology by minimizing heat loss, improving heat transfer, and mitigating the impact of solar intermittency. Finally, the review identifies challenges associated with PDC technology and explores how integration with these advanced strategies can contribute to more efficient and sustainable energy conversion.
