One-Dimensional Si/SiO2 Photonic Crystals Filter for Thermophotovoltaic Applications
Authors: , , ,
Abstract: In this paper, a one - dimensional Si/SiO2 photonic crystals (1D-PhCs) is optimized for potential application as thermophotovoltaic (TPV) optical filter. The performance of the proposed structure, 1D eightlayer Si/SiO2 of thermophotovoltaic system, is studied. The effect of the thickness of layers, incidence angle and number of periods on the spectral reflectance has been investigated by rigorous coupled-wave analysis (RCWA) method. Both the original proposed and the modified structures were prepared through a magnetron sputtering technique. The measured results are in good agreement with the simulated results. The spectral efficiency value of the modified structure is 33.5%at emitter temperature of about 1500 K .The measured results and simulated results have shown that the modification introduced in the 1D Si/SiO2 PhC has significantly improved the system performance.
