“…Passive cooling in point focus systems has been proven to successfully manage the PV cell temperature with different heatsink geometries and for high concentration ratios for up to 2000 suns [35,39]. For ultrahigh concentration ratios, solar cells of 1 mm 2 or smaller can maintain the cell temperature below the maximum recommended operating temperature with a conventional flat-plate heatsink up to 10,000 suns [40].…”

“…Many types of research show the ability to use passive heat sink to keep panel efficiently (especially in 500suns) [12][13][14][15][16][17][18][19], the passive cooling fin structure can be shown in Figure 3 [19]. The nomenclature used (Figure 3) in the present work is: spacing (s), pitch (p), height (H), thickness (t), length (L), base width (W), and base thickness (tb) [19].…”

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 ...
