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.

“…Unfortunately, the typical single-component heat-transfer fluids (e.g., glycols, mineral oils, water etc. ), which are frequently employed in the PT or PVT systems, do not yield significant enhancements due to their fixed spectral properties [ 15 , 16 , 17 ]. In addition, the limited spectral transmittance of these single-component working fluids does not adequately match the spectral responsivity of the commercial PV technology available.…”

“…In addition, the limited spectral transmittance of these single-component working fluids does not adequately match the spectral responsivity of the commercial PV technology available. This further decreases the potential of the PVT systems to efficiently generate clean electricity when such fluids are used [ 15 , 16 , 17 ]. Therefore, alongside the developments in PVT architecture, there is the concurrent requirement to identify and/or develop new high-performance heat-transfer fluids whose spectral properties can be controlled, adapted, and optimised for specific solar energy applications.…”

Exploiting solar energy using photo-thermal (PT) and/or hybridised photovoltaic/thermal (PVT) systems can represent a viable alternative to the growing demand for renewable energy. For large-scale implementation, such systems require thermal fluids able to enhance the combined conversion efficiency achievable by controlling the ‘thermal’ and ‘electrical’ components of the solar spectrum. Nanofluids are typically employed for these purposes and they should exhibit high heat-transfer capabilities and optical properties tuned towards the peak performance spectral window of the photovoltaic (PV) component. In this work, novel nanofluids, composed of highly luminescent organic molecules and Ag nanoparticles dispersed within a base fluid, were tested for PT and PVT applications. These nanofluids were designed to mimic the behaviour of luminescent down-shifting molecules while offering enhanced thermo-physical characteristics over the host base fluid. The nanofluids’ conversion efficiency was evaluated under a standard AM1.5G weighted solar spectrum. The results revealed that the Ag nanoparticles’ inclusion in the composite fluid has the potential to improve the total solar energy conversion. The nanoparticles’ presence minimizes the losses in the electrical power component of the PVT systems as the thermal conversion increases. The enhanced performances recorded suggest that these nanofluids could represent suitable candidates for solar energy conversion applications.

Photovoltaic (PV) cells are one of the most common devices to harvest solar radiation and convert it into usable electrical power. However, normal silicone‐based photovoltaic cells work best within the visible light region. Conventional PV panels can use 15–30% of the total energy received, while the remainder is reflected or converted into waste heat. Not only do other wavelengths have lower conversion efficiencies, but they may also increase the cell surface temperature and decrease its overall efficiency. To solve this problem, spectral beam splitting is a potential approach for converting solar energy efficiently. Even though spectral‐splitting systems have high theoretical conversion efficiencies, they have not yet reached the commercial level. The current study describes the advancements in beam‐splitting systems based on thermal PV cells, multijunction cells, nano‐film, conventional, and nanofluids over the last decade. The mechanisms of various splitting system techniques and several hybrid applications are thoroughly discussed in order to provide a comprehensive understanding of solar energy utilization and the considerations influencing system efficiency. Even though the cost increase can be offset by the increased energy conversion efficiency and controlled wavelengths, the system's stability must be addressed for future practical applications.
