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.

“…The main advantage of Concentrated system is the reduction of area of the PV cell area and being replaced by optical and beam splitting elements. The optical elements are more cost effective compared to the PV material [8]. The concentrated system must be enabled with a heat dissipation method to avoid the thermal stress [2] and efficiency deterioration.…”

“…In addition, CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency. The most important factor in CPVT is the concentration coefficient, the higher the magnitude of this factor, would lead the higher concentration of sunlight and solar energy density . with increasing of the solar radiation density, the temperature increase in the central region, then the thermal energy production increases .…”

In this research, a genetic algorithm has been used to optimize the focal area of the parabolic trough concentration photovoltaic/thermal. First, based on the physical and thermodynamic variables, the system modeling was performed; then, by changing the variables were calculated the effect of these parameters on the electrical and thermal efficiencies. In the next step, the optimization was conducted by the mentioned algorithms. The objective function consists of two targets of electrical efficiency combined with thermal efficiency. The optimization variables include the length of the system, the pipe diameter, the collector diameter, mass flow rate, and the photovoltaic cell width. After running the program in the normal mode, the highest electrical and thermal efficiencies were 0.2063 and 0.4473 for the length of 10 m, the collector diameter of 1.2 m, the flow rate of 0.15 kg/s, the pipe diameter of 0.03 m, and the photovoltaic cell width of 0.02 m. According to the genetic algorithm, the optimal answer for the total efficiency of this system is 0.84737.
