Background: The efficiency of a thermal conversion system requires adequate radiative properties. In a thermophotovoltaic system, the optical filter plays a key role into the overall performance of the system. The purpose of this paper is to study a one-dimensional TiO2/SiO2 photonic crystal for application as thermophotovoltaic optical filter.
Methods: The influence of the layers’ thicknesses, incidence angle, and number of periods on the spectral reflectance has been investigated through the transfer matrix method.
Results: It was found that, when one varies the number of layers from 6 to 12, an improvement of the optical properties of the spectral filter is observed. The surface wave through a film of photonic crystal generates a resonant transmission for a truncated structure.
Conclusions: These results are in conformity with those found in the literature.
Key words: Thermophotovoltaic / Spectral filter / Transfer matrix method / Photonic crystal / Multilayered structures
