Photovoltaic-thermal (PV/T) technology, combines the benefits of both solar photovoltaic (PV) and solar thermal systems into a single integrated solution. It is a promising renewable energy technology that maximizes solar energy utilization and offers multiple benefits for sustainable power generation. A review and discussion of both active and passive thermal management solutions for PV technology is included in this paper. Using fins on the back of PV is the focus of this paper in terms of its design and performance parameters. Fins are used in air, fluid, nanofluid and PCM cooling PV/T systems. Installing them in these systems improves their performance and increases their electrical and thermal efficiency together in rate range between 8 and 10. Furthermore, this article examines different approaches to designing and implementing systems, as well as how to optimize results, in addition to exploring potential problems and opportunities. Aiming at creating, manufacturing, utilizing, and potentially promoting high-performance photovoltaic-based technologies and systems which include fins are the purpose of this article. © 2023 The Authors
