Summary Integration of solar concentrators with photovoltaic (PV) systems reduces the required number of PV panels, which often account for the major costs of PV systems. The linear Fresnel reflector mirror is considered more effective because of its simplicity and effortless fabrication. An experimental test rig of a concentrated PV/thermal system that employs a linear configuration and horizontal absorber was built for evaluating its electrical and thermal performances. The considered concentrator consists of various widths of flat glass mirrors, which positioned with different angles, and with sun light focusing on the PV cells that fixed over an active cooling system. The experimental investigation of the proposed concentrated PV/thermal system shows that higher electrical and thermal efficiencies can be achieved at comparatively high temperature levels than that typically utilized in a nonconcentrated PV/thermal system. The characteristics of PV cells also indicate that the electrical efficiency values in case of no concentration and with concentration ratio of 6.0 are 9.6%, and 11%, respectively. The measured values for the inlet and outlet cooling water temperatures of the receiver showed that the maximum outlet temperature reached was 75°C with a flow rate of 0.025 L/min, and the product thermal efficiency was 62.3%. These obtained results illustrate an adequate and good thermal and electrical performance under the meteorological weather conditions of the province of Al‐Karak in Jordan.

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.

“…Spectrum splitting systems should be optimally designed, which divides the spectral bands that optimally match the PV cell spectral response so that the cutoff wavelengths should be optimized. The optimization and limiting efficiency have been explored for the photovoltaic/thermal spectrum splitting systems . However, most of the previous photovoltaic/thermal spectrum splitting systems divided the incident spectrum into two segments, which cannot make full use of high‐energy photons because the thermalization loss cannot be reduced effectively.…”

Maximum efficiencies and parametric optimum designs of concentrating photovoltaic cell/heat engine systems with three‐band spectrum split

Summary The irreversible model of a concentrating photovoltaic cell/heat engine system with three‐band spectrum splitting is established for the further prediction of the conversion efficiency of photovoltaic/thermal systems, in which the internal and external irreversible losses are considered. An update efficiency of the spectrum splitting system is derived, from which the maximum efficiency of the whole system is calculated. The influences of the area ratio of two subsystems on the systemic performance are analyzed in detail. The reasonable ranges of the area ratio are given. The maximum efficiency and the corresponding critical parameters are obtained under different operating conditions. It is found that the introduction of the area ratio is significant for accurate predictions of systemic performances and the maximum efficiency can attain 77.64%, which significantly exceeds that of an individual concentrating photovoltaic cell and solar‐driven heat engine at the same concentration condition. The performance characteristics of the two‐band spectrum splitting system including the photovoltaic cell and heat engine may be directly obtained from the present model. Moreover, the performances of three‐ and two‐band spectrum splitting systems are compared, and consequently, the advantages of the three‐band spectrum splitting system are revealed.
