“…Firstly, the indicator that can be brought out is the value of the wavelength at the extremum of the curve which is around 2000 nm for the three Figure 10, Figure 11, Figure 12. This obtained value is in agreement with the authors [3,16]. Secondly, we observe that Figure 10 presents the maximum values of the emittance between 12*10 10 and 15.5*10 10 W.m -2 .µm -1 corresponding to the value of λ = 2000 nm; and these values are very distinct.…”

“…The concept of TPV system is to convert thermal energy from a heat source (sun or combustion reaction) directly into electrical energy by means of emitter, filter and photocells [2]. TPV system is composed of four component which are heat source, thermal emitter, spectral filter and arrays of infrared sensitive photovoltaic cells as it is shown in the Figure 1 [3].…”

Thermo PhotoVoltaic (TPV) system convert into electrical energy the radiation emitted from an artificial heat source (i.e., solar or combustion) by the use of photovoltaic cells. In the last decade, TPV system has gained an increasing attention as cogeneration system for the distributed generation sector. Nevertheless, these systems are not fully developed and studied: several aspects need to be further investigated and completely understood. In this study, we modeled and investigated by performing numerical simulation on the feasibility of the TPV system exploiting waste heat energy during biomass combustion. To achieve this goal, we considered a TPV system in which we evaluated and analyzed the waste heat flux resulting from the combustion of the palm nuts shells as well as the corresponding temperature received at the surface of the TPV Thermal-emitter. Furthermore, we evaluated the heat intensity. Results obtained shows that the average temperature at the TPV absorber-emitter is around 1600k. Different variation of the net heat flux at the TPV absorber-emitter are observed for different position. The maximum heat intensity is around 15*1010 W.m-2.µm-1 for a wave length of 2000 nm. These results indicate that the model presented herein is therefore suitable for the design of the TPV system.

“…Due to these features, it is possible to control and tune light in PhCs [4], thus opening a new perspective for information processing and technological applications such as chips [5,6], filters [7,8], lasers [9,10], waveguides [11], integrated photonic circuits, sensors [12,13] and thin film photovoltaic cells [14,15], to mention but a few. As is well known, there exist many sort of materials used to form tunable PhCs, such as semiconductors [16], metals [17], superconductors [18,19], metamaterials [20] and liquid crystals [21], among others.…”

A Multichannel Superconductor-Based Photonic Crystal Optical Filter Tunable in the Visible and Telecom Windows at Cryogenic Temperature

We design and evaluate the performance of a one-dimensional photonic crystal (PhC) optical filter that comprises the integration of alternating layers of a barium titanate ferroelectric (BaTiO3) and an yttrium oxide dielectric (Y2O3), with a critical high-temperature superconductor defect, yttrium–barium–copper oxide (YBa2Cu3O7−X), resulting in the (BTO/Y2O3)N/YBCO/(Y2O3/BTO)N multilayered nanostructure array. Here, we demonstrate that such a nanosystem allows for routing and switching optical signals at well-defined wavelengths, either in the visible or the near-infrared spectral regions—the latter as required in optical telecommunication channels. By tailoring the superconductor layer thickness, the multilayer period number N, the temperature and the direction of incident light, we provide a computational test-bed for the implementation of a PhC-optical filter that works for both wavelength-division multiplexing in the 300–800 nm region and for high-Q filtering in the 1300–1800 nm range. In particular, we show that the filter’s quality factor of resonances Q increases with the number of multilayers—it shows an exponential scaling with N (e.g., in the telecom C-band, Q≈470 for N=8). In the telecom region, the light transmission slightly shifts towards longer wavelengths with increasing temperature; this occurs at an average rate of 0.25 nm/K in the range from 20 to 80 K, for N=5 at normal incidence. This rate can be enhanced, and the filter can thus be used for temperature sensing in the NIR range. Moreover, the filter works at cryogenic temperature environments (e.g., in outer space conditions) and can be integrated into either photonic and optoelectronic circuits or in devices for the transmission of information.

“…On the other hand, the metal oxide layers such as Al2O3, TiO2, SiO2, MgO2, and ZrO2 have been used to act as an energy barriers forrestraining charge recombination [15][16][17][18][19][20]. In visible and near infrared region (NIR), the Zirconia dioxide material ZrO2 host possesses a high physical, chemical stability and optical transparency.…”
