“…The results showed that a 50% increase in the overall efficiency was achieved when ferrofluid was placed under alternating magnetic fields with frequency of 50 Hz. An et al, [42] conduct experiments for the enhancement of collectors and thermal energy at conditions of fluid temperature above 100 °C. The overall efficiency of PVT collector flowing with nanofluid filters increased by 17.9%.…”

Nanofluids have received considerable attention in the past decades. Nanofluid is produced by dispersing nanoparticles into a base fluid with a typical size of less than 100 nm in a liquid. Nanofluids have been proposed as a replacement for conventional cooling fluid because of their enhanced thermal properties. This review presents descriptions and previous works conducted on the performance analysis of nanofluidbased photovoltaic thermal (PVT) collectors. Results on the performance analyses of nanofluid-based PVT collectors are summarised. The use of nanofluid as a heat transfer fluid in PVT collectors shows enhanced performance. The performance of nanofluidsbased PVT collector will increase in terms of overall efficiency compared with conventional fluids. Thus, small and compact nanofluid-based PVT collectors can be manufactured, thereby reducing the weight, energy and cost of manufacturing.

“…[35] In the case of an optical splitting film, spectral splitting is achieved by using the film to reflect desirable sunlight with wavelengths of 400~1 100 nm to the PV cells for electricity generation, while sunlight with wavelengths of 1 100~2 500 nm is transmitted to heat a thermal absorber. [36] Several theoretical and experimental studies have validated the use of spectral splitting methods based on nanofluids and optical splitting films to realize full solar spectrum utilization. However, their practical application is severely limited due to precise optical path requirements that, if unmet, can lead to serious light leakage.…”

Conventional Si photovoltaic cells cannot convert full solar energy spectrum (400~2 500 nm) into electricity owing to the mismatch between Si band gap and broad range of solar photon energies. Transparent silicon PV cell allows sunlight in the wavelength of 1 100~2 500 nm to transmit through itself and irradiate on the thermal absorber below. The traditional photon management method based on texturing silicon layer with nanostructures can enhance 400~1 100 nm absorptivity and 1 1002 500 nm transmittance of transparent silicon PV cell. However, an increase in charge carrier capture and a decrease in electricity generation efficiency are often observed with this. In this study, a novel spectral splitting method based on frontlocated wavelength-sized TiO 2 biomimetic moth-eye nanophotonic structure is put forward, which can inhibit the increase of charge carrier capture and recombination. The biomimetic moth-eye nanophotonic structure was optimized by using finitedifference time-domain (FDTD) method to achieve excellent photon anti-reflection and scattering properties. The calculation results indicated that the absorption factor and transmission factor of transparent silicon PV cell could be increased from 46% to 58% and from 11% to 14%; the relative power conversion efficiency enhancement rate and relative incident radiation power enhancement rate was 32% and 27% when the TiO 2 biomimetic moth-eye was adopted.

On the other hand, many researchers put the concentrate on theoretical efficiency and optimization.…”

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.
