“…In fact, Moriji et al firstly introduced the volumetric absorption combined spectral beam splitter for CPV/T systems. But the results indicated that the electrical efficiency was only 3.8% relative to the incident light when the receiver incorporated with combined solid (semiconductor doped glass‐SDG) and liquid (propylene glycol‐PG) filters under a parabolic trough concentrator . The low electrical efficiency is due to several reasons including PG optical properties deviation from the ideal filter properties and the lack of uniform illumination along the solar cells .…”

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.

“…It divides the incoming spectrum into several segments based on the photon energy, and the split segments should be sent to the most efficient receivers . This method is an efficient method to alleviate the energy losses in the PV cell, and the thermal cycle is not limited by the temperature of the PV cell . Since the concept of the spectrum splitting was first mentioned by Jackson in early 1955, many theoretical and experimental studies have been carried out for the purpose of the performance improvement of the SSS.…”

The spectrum splitting system (SSS) is an efficient approach to relieve the energy losses in the solar cell and boost the efficiency of solar energy utilization. A model of the concentrated solar spectrum splitting photovoltaic (PV) cell-gas turbine (GT) hybrid system is established to evaluate the performance of the system and predict the maximum efficiency. The numerical calculations show that the area ratio of the solar collector to the PV cell significantly affects the maximum efficiency of the spectrum system, but most of the previous studies are not considered. The maximum efficiency of the system is 50.6% when the parameters including the cell voltage, collector temperature, and band gap energy of the PV cell are optimized at the same areas of the collector and PV cell. The proposed SSS can achieve the maximum efficiency of 52.3% when the area ratio of the collector to the PV cell is further optimized. The results obtained are compared with those of a single concentrating PV cell or solar-powered GT, and consequently, the advantages of a concentrating spectrum splitting PV cell-GT hybrid system are revealed.

“…To a rectangular micro-channel, the liquid flow and conjugated heat transfer performance of single-phase laminar flow in it equipped with longitudinal vortex generators are numerically investigated by Ebrahimi et al [12]. Some of other cooling studies [13][14][15][16][17] which relied on numerical techniques and their experiments have been also conducted on the flow and heat transfer characteristics of PV thermal receiver. However, despite their high heat-transfer performance, micro-channels are inappropriate because of their huge pressure drop.…”

The viability of a plate receiver for an array of densely packed photovoltaic cells with a point focusing solar concentrator has been investigated. A cooling receiver being similar to a multi-channel receiver was designed and a thermal resistance model was developed to optimize the geometric parameters. Furthermore, the simulation results found that when the receiver fin height, channel width, and width of the fin wall is 15, 1, and 5.8 mm, respectively, the total thermal resistance could be less than 4 cm 2°C /W under a constant volumetric flow rate of 0.1 L/s. A physical prototype has been built according to the simulation results. A performance test has been conducted to investigate the temperature distribution and the thermal performance. The experimental results reveal that the new design of the plate receiver has a desirable working performance and it is acceptable for the cooling application of photovoltaic cells which expose to high heat fluxes.
