“…They proved that the intermittent tracking mode is more efficient than the continuous tracking mode for the CPC. A north-south axis external concentrating TCPC with heat-pipe evacuated solar collector tubes, crank rod transmission mechanism, and electric device was presented by Wang et al [57] (Figure 26). They proved that the intermittent tracking mode is more efficient than the continuous tracking mode for the CPC.…”

Invention of evacuated tube heat pipe solar collectors (HPSCs) was a huge step forward towards resolving the challenges of conventional solar systems due to their unique features and advantages. This has led to their utilization in a wide range of solar applications surpassing other conventional collectors. However, relatively low thermal efficiency of heat pipe solar (HPS) systems is still the major challenge of solar industry evidenced by numerous studies conducted mainly during the last decade to improve their efficiency. To date, several review papers have been published summarizing studies relevant to utilization of HPSCs in various thermal applications. However, to the authors' knowledge, a comprehensive review which surveys and provides an overview of the studies undertaken to improve the thermal performance of HPS systems (mainly during the last decade) by implementing different strategies has not been published to date. This review paper summarizes all the proposed strategies to improve the thermal efficiency of different industrial, domestic, and innovative HPS systems. First, the concept, structure, and operational principles of HPSCs are introduced concisely. Then, novel structures and designs of HPSCs aiming to increase the thermal efficiency of the collector as the most important component of the solar system is reviewed. This is followed by a comprehensive review of various methods to store solar energy more efficiently, increase solar system's operation time, increase overall efficiency by turning the solar system into a multipurpose system, enhance heat transmission in the solar system, and implement new solar loop and heat pipe working fluids with better heat transfer characteristics. Finally, research gaps in this field are identified and some future research trends and directions are recommended.

Compound parabolic concentrator (CPC) has been gaining ever-increasing attention from academic researchers and industrial developers owing to its stationary feature for solar energy collection with a higher efficiency. As a low concentration concentrator with a larger acceptance angle and without a tracking requirement, it is an attractive solution to improve the system performance and reduce the cost of photovoltaic (PV) system, solar thermal system, daylighting and lighting systems, etc. This study will present a comprehensive and up-to-date review of its design principles for miscellaneous configurations, applications, performance predictions and technological advances. Numerous technically focused studies since 2000 will be introduced and summarized. Finally, the outlook focusing on CPC designs and improvements will be proposed.
