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.

Solar panel comprises some solar cells in series and parallel arrangements converting sunlight into electrical current in usable level. However, the cell arrangement causes large surface area exposed to sunlight that tends to be heat absorbent. Existing study shows that the efficiency of solar cell decreases about 0.5% for each 1℃-surface temperature increment. Various cooling systems for solar cells have been offered by many researchers. This paper proposes a passive cooling system that combines water-filled aluminium blocks and heat-sinks. The water-filled aluminium blocks absorb heat from the back of solar cells and the heat-sinks release this heat to the air. The experimental assessment showed that the proposed method is able to reduce surface temperatures about 11.91% lower than the non -cooled solar panel. Compared to the existing methods, the proposed coolant achieved 5.08% and 7.37% lower surface temperatures than water and heat-sink coolant subsequently. The proposed cooling system also exerted at least 6.28% higher power than the other methods.

“…Aldossary shows the outlet temperature of water cooling can be reached 90°C when it is accessed to a large scales HCPV plant. The heat can be used for heat pump or other thermal application [26]. The active cooling varies from many different types, the paper will discuss them in the following section.…”

“…Royne claimed passive cooling system can be used to single cell geometries in 1000 suns. However, more study shows that passive cooling is not efficient enough to cool down the cell especially in high environment temperature [23][24][25][26]. Aldossary concluded that active cooling can maintain PV operation efficiency under operating temperature limit and avoid solar cell lifetime degradation [26].…”

AbstractHigh concentration photovoltaics (HCPV) have become popular new types of solar technology. Compared to traditional photovoltaic panels, HCPV systems are potentially more efficient and cost-effective. However, HCPV's operation will cause high temperature on the panel surface, which causes a heat waste and deficiency of HCPV. Meanwhile, the anaerobic production and desalination plant need a highly demand of heat resource. The paper uses TRNSYS software to design a hybridization system with 500 suns concentration's HCPV, multi-stage flash desalination and anaerobic tank. The 0.01 m2 size HCPV system achieves a max electricity output at 300 W. Meanwhile the hybridization can operate desalination plant with 0.5 distillation ratio and anaerobic digestion at 3.2 m3 per hour. The study of a graduate research of the hybridization of high concentrated solar panel and anaerobic production and desalination would fit the call in the graduate division and it is consistent with the division objectives. Furthermore, the study is relevant to the ASEE division's mission and the scope is interdisciplinary including design, development and research. The research paper is relevant to Chi Xu's Ph.D. dissertation. Furthermore, the information is also used in a graduate level public works engineering and management class that is offered each fall semester. This makes it relevant to the theme of the ASEE Graduate Studies Division. IntroductionThe solar energy is an ideal energy can gain from the sun, as a type of renewable energy, solar energy has its advantage: widespread, low contamination and flexibility. High concentrated photovoltaics is new solar technology which can produce electricity cost-effectively. By using a reflection system to concentrate solar radiation can decrease cost and increase the efficiency. HCPV uses cooling system to cool down the high level heat received from solar concentration. However, cooling system can't use the potential energy from the heat, thus the heat is 'waste'. In order to reuse the energy and demonstrate the concept of renewable energy, the paper will design the hybridization the ...
