“…The system is designed, and a 3D optical model is fully developed with Monte Carlo Ray Tracing (MCRT) method in order to simulate the radiation transmission within the system. The MCRT method has been utilized successfully to investigate the performance of PTCs [20][21][22], Parabolic Dish System [23][24][25], and Solar Power Tower System [26][27][28][29][30][31]. Based on the model, firstly, the local solar flux distribution on the absorber surface and the optical efficiency are computed.…”

“…[48,49] Many studies had been reported that convection, conduction, and radiation losses limited the temperature of the thermal absorber at high temperature. [50,51,52] The TE was enclosed in an insulating layer to inhibit conduction and convection heat losses. The transparent silica aerogel had high transmittance in solar spectrum, low emissivity in mid infrared and low thermal conductivity.…”

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.

“…It can overcome the previous drawbacks, and has drawn more and more attention in recent years. The fundamental principles of the radiative temperature measurement are Planck's law, Wien's law, and Stefan-Boltzmann law [9,10]. However, due to the impact of the spectral emissivity, the measured temperature is not the real temperature of the object.…”

The infrared temperature measurement technique has been applied in various fields with the development of charge coupled device. In the problem of metal surface temperature measurement, if the surface is covered by participating media, the traditional infrared temperature measurement technique will lead to intolerable measurement errors. In this work, the infrared temperature measurement problem was solved by the source multi-flux method. On this base, the impact of the flue gas thickness and surface temperature on the apparent temperature measured by the charge coupled device was analyzed. Furthermore, the corresponding experimental system was set up. And the experimental results were found to have a good agreement with the simulated results. Finally, the idea of modification for the infrared temperature measurement by inverse method was proposed.
