Abstract

This paper provides an overview of passive cooling technologies used in photovoltaic (PV) and photovoltaic-thermal (PVT) modules that serve as an alternative energy source for countries with high solar irradiation and cooling requirements. Passive cooling is an attractive solution for PV panel applications because, unlike active cooling methods, it does not require external energy for the cooling process. The main objective of this paper is to provide a comprehensive overview of passive cooling technologies and their applications in PV and PVT modules while highlighting the challenges and potential areas for future research in this field. Various cooling techniques are discussed, including radiative, air, liquid, and phase change materials (PCM) based methods, with particular emphasis on their efficiency and effectiveness in different scenarios. Previous studies addressing advances in improving the electrical and thermal efficiency of PV and PVT modules are also reviewed. This paper covers a wide range of cooling techniques, including full-spectrum, airflow, fin, heat pipe, and nanofluids, as well as PV-PCM and PVT-PCM. Overall, the paper highlights the potential of passive cooling techniques for the effective and efficient use of solar energy in PV and PVT systems. It also highlights the challenges and future research prospects associated with these technologies. In summary, this study provides valuable insight into the potential of passive cooling technologies as a means to improve the performance and efficiency of solar energy systems, proving useful to researchers and engineers in the renewable energy and sustainable development fields, particularly those focused on developing cooling systems for PV and PVT applications.
