Summary Solar energy is going to play a crucial role in the future energy scenario of the world that conducts interests to solar‐to‐hydrogen as a means of achieving a clean energy carrier. Hydrogen is a sustainable energy carrier, capable of substituting fossil fuels and decreasing carbon dioxide (CO2) emission to save the world from global warming. Hydrogen production from ubiquitous sustainable solar energy and an abundantly available water is an environmentally friendly solution for globally increasing energy demands and ensures long‐term energy security. Among various solar hydrogen production routes, this study concentrates on solar thermolysis, solar thermal hydrogen via electrolysis, thermochemical water splitting, fossil fuels decarbonization, and photovoltaic‐based hydrogen production with special focus on the concentrated photovoltaic (CPV) system. Energy management and thermodynamic analysis of CPV‐based hydrogen production as the near‐term sustainable option are developed. The capability of three electrolysis systems including alkaline water electrolysis (AWE), polymer electrolyte membrane electrolysis, and solid oxide electrolysis for coupling to solar systems for H2 production is discussed. Since the cost of solar hydrogen has a very large range because of the various employed technologies, the challenges, pros and cons of the different methods, and the commercialization processes are also noticed. Among three electrolysis technologies considered for postulated solar hydrogen economy, AWE is found the most mature to integrate with the CPV system. Although substantial progresses have been made in solar hydrogen production technologies, the review indicates that these systems require further maturation to emulate the produced grid‐based hydrogen.

“…The use of kaleidoscope along with a primary optical element can reduce the tracking requirement of a CPV system. Widyolar et al [3] simulated various combinations of solar cells with different types of spectral beam splitting (ideal filter, interference filter, and semitransparent/back reflected solar cells) and concentrated solar power. The study also compared the economic analysis in comparison with c-Si flat panel.…”

Concentrated Photovoltaic (CPV) is an attractive alternative to fossil fuels due to its ability to reduce the PV cell area and increase the energy outputs using low cost optics. This review paper, details the recent experimental and simulation studies conducted in the field related to CPV in the past few years. The paper details the general expressions used for experimental works, followed by sections detailing the studies conducted on the optics, photovoltaics, heat dissipation and integration application. Different designs proposed by the researchers has also been briefly described. The findings shows the potential for CPV and CPV/T systems is promising with overall efficiencies greater than 60%.

“…Meanwhile, it preserved the dispatchability of the CSP system's thermal energy storage. Widyolar et al (2018) [48] firstly simulated and optimized the hybrid solar CPV/CSP parabolic trough collector (PTC) systems (single stage and novel two stage design) with spectral and temperature optimization, which integrated with different spectral beam splitting (SBS) approaches (ideal, interference filter, and novel integrated semi-transparent/back-reflecting solar cell filters) with different solar cells (c-Si, CdTe, GaAs, InGaP), to maximise the solar-to-electric conversion. According to Yaping et al (2015) [49] and Widyolar et al (2017) [50], out-of-band transmission in a semi-transparent triple junction cell could be 87% (ignoring grid contact shading losses) [49], and out-of-band reflectance of a bare GaAs cell was reported to be 92% (closer to 83% with assumed encapsulent losses) [50].…”

Concentrated Photovoltaics (CPV) technology, as an energy saving method which can directly generate electricity from the Sun, has attracted an ever-increasing attention with the deepening worldwide energy crisis. However, operating temperature is one of the main concerns that affect the CPV system. Excess cell temperature causes electrical conversion efficiency loss and cell lifespan decrease. Thus, reasonable cooling methods should decrease the operating temperature and balance the flare inhomogeneity. They also need to display high reliability, low power consumption, and convenient installation. This paper presented the architectural, commercial, and industrial usage of CPV system, reviewed the recent research developments of different cooling techniques of CPV systems during last few years, including the spectral beam splitting technology, cogeneration power technology, commonly used and promising cooling techniques, active and passive cooling methods. It also analysed the design considerations of the cooling methods in CPV systems, introduced the classification and basic working principles and provided a thorough compilation of different cooling techniques with their advantages, current research limitations, challenges, and possible further research directions. The aim of this work is to find the research gap and recommend feasible research direction of cooling technologies for CPV systems.
