Abstract

Abstract: Harvesting energy from the sun is a promising technology to resolve the ongoing energy crisis. Solar photovoltaic (PV) and photovoltaic/thermal (PV/T) systems are mainstream solar energy conversion technologies that enable duple functions to obtain both electrical and thermal energy. However, in practice, emerging problems (uneven temperature distribution, limited cooling effect, freezing issues, high initial costs, etc.) have hindered the development and progress of these technologies. To overcome the aforementioned barriers, a heat pipe was introduced as an effective heat transfer device with passive operation characteristics. The assimilation of cutting-edge thermoelectric (TE), phase change material (PCM) and the development of integrated photovoltaic (BIPV), heat pump, and nanotechnologies have also been explored to achieve higher overall efficiency. This paper focuses on the integration of various heat pipes with solar PV systems and innovative technologies from historical development and recent advancements. In addition, the major observations and challenges are highlighted, and the prospects for future development are corroborated. This work is dedicated to opening new horizons and providing suggestions in this research field, enabling in-depth and broad exploration. Highlights: Heat pipes based solar photovoltaic and photovoltaic/thermal systems are reviewed. The combination of innovative technologies in these systems is summarized. Using heat pipes in these systems leads to enhanced performance. Challenges and future suggestions of such technologies are discussed.
