ABSTRACT

The efficiency of Photovoltaic (PV) and Photovoltaic/Thermal (PV/T) solar systems is significantly compromised by the increase in operating temperature. This review paper synthesizes recent advancements in integrated cooling strategies, focusing on the synergistic application of N6no Phése Chónge M6teriőls (№6по-РСМ), №6nofluids, and Finned Structures. Analysis of recent experimental and numerical studies reveals that hybrid cooling techniques, such as the combination of nanofluid circulation with finned PCM heat sinks, can lead to substantial performance improvements. Key findings indicate electrical efficiency enhancements up to 23.9% and thermal efficiency improvements reaching 83.3%, alongside significant PV module temperature reduction (e.g., 24.57 °C decrease). The paper systematically reviews the mechanisms, performance metrics, and optimization challenges associated with each cooling component and their integrated systems, providing a comprehensive overview for future research and practical implementation in high-efficiency solar energy systems.
