Abstract
Thermophotovoltaic power generation has recently attracted considerable attention as a means to use waste heat. In order to improve the efficiency of TPV power generation, it is necessary to develop spectrally and directionally selective thermal emitters. By taking advantage of high refractive index of β-FeSi2 (n ∼ 5), we have successfully demonstrated that the spectrally selective emitter is fabricated by sputtering a β-FeSi2 thin film on a polished 304 stainless steel substrate. A noble bottom up process to fabricate periodic array of β-FeSi2 nanopillars, which are necessary for the directionally selective emission, will be also presented.
