“…In this article, the spectral beam splitting mechanism will be achieved by the volumetric absorption combined spectral beam splitter which consists of the infrared light absorber‐fluid based filter and the visible light absorber‐solid based filter. Compared with cooling liquids used in traditional CPV/T systems, the property requirement of the fluid based filter utilized in spectral splitting CPV/T systems is much stricter . Firstly, the fluid based filter should have high transmittance in the silicon‐particular spectral response range, and effectively absorb other wavelengths.…”

Summary Spectral beam splitting is a promising technology to achieve the maximum electrical and thermal outputs from concentrating photovoltaic/thermal (CPV/T) systems simultaneously. In this article, a novel CPV/T receiver is proposed by incorporating a fluid based filter together with a solid absorptive filter. The geometry of the receiver is developed for a designed linear flat mirror concentrator. According to the optical transmittance of both fluid based filters and solid absorptive filters, as well as their corresponding merit functions, four fluid filters and two solid filters are determined to be the candidates of the combined filter for the silicon concentrator solar cell. Then, a complete solar radiation propagation process from concentrator to the designed CPV/T receiver is simulated using ray tracing software‐LightTools. The results show that the surface illumination uniformity of the PV module filtered by each combined filter under the linear flat mirror concentrator is higher than 96%. Using 5 g/L CoSO4 solution and HB650 as the combined filter, 33.67% of the concentrated light can be directed to the PV module with the remainder collected by the filter as thermal energy and the silicon CPV cells can convert 27.06% of this energy into electrical power. This contributes to the fact that 92.43% of the light striking the PV module is within 650‐1100 nm, which is the spectral response range of the cell can work efficiently. The total efficiency of 49.88% can be achieved with such a filter and the electrical efficiency is 9.1% with respect to the total incident power on the receiver.

Hybrid photovoltaic/ thermal systems are very promising clean energy harvesting devices where they can be used either standalone system or can be incorporated with other systems. In this study, historical developments leading to current Hybrid Photovoltaic/Thermal (HPV/T) systems as it is used today and global findings to enhance the performance of HPV/T system through state-of-the-art analyses are presented in a thematic way. The findings from initial studies on the HPV/T systems is revealed in an historical way and rest of sections are formed based on selected criteria. The paper covers basic and advanced type collectors, working fluids, analyzing methods to assess performance, thermodynamic approaches, optimization of design parameters and mass flow rates, techniques to enhance performance and comparative studies. Especially, various parametric studies to optimize performance of the HPV/T with respect to selected parameters including different types of absorbers, packing factor, cooling schemes, working fluid types, modifications at different sections of the system are comprehensively investigated. Based on the conclusions, the variation in electrical and thermal efficiencies are mainly in the scope of this study. It is observed from the literature that solar HPV/T system has a great potential to be one of the up and coming clean energy technology.

“…Initially, type of the employed PV cells affects the PV module electrical performance. Depending upon the kind of these cells and climatic circumstances, a standard PV module transforms (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) % of the falling solar radiation into electricity. The residue of solar radiation is transferred into heat, which elevates the module temperature and reduces its efficiency [1].…”

The fall angle of sun rays on the surface of a photovoltaic PV panel and its temperature is negatively affecting the panel electrical energy produced and efficiency. The fall angle problem was commonly solved by using a dual-axis solar tracker that continually maintains the panel orthogonally positioning to the sun rays all day long. This leads to maximum absorption for solar radiation necessary to produce maximum amount of energy and maintain high level of electrical efficiency. To solve the PV panel temperature problem, a Water-Flow Double Glazing WFDG technique has been introduced as a new cooling tool to reduce the panel temperature. In this paper, an integration design of the water glazing system with a dual-axis tracker has been accomplished and experimentally tested in order to enhance the PV panel efficiency, especially at hot climates. The proposed glazing system can simultaneously perform two functions, firstly, working as a cooling tool for reducing the stored heat in the PV panel during its work and secondly as an optical filter for sun light spectrum. Optimum design factors with their levels for the glazing system were calculated according to Taguchi method. Test experiments were carried out in Baghdad city on the 20th and 21st July 2016 on the tracker with and without using the WFDG system. The obtained results show that, the PV panel temperature with using the WFDG system was significantly dropped by 44% and its efficiency increased maximally by 36.6% at solar irradiance of 1213W/m2 as compared with conventional one.
