THERMOPHOTOVOLTAIC CONVERSION MEMBER

A thermophotovoltaic conversion member able to selectively absorb and emit light of a short wavelength, provided with a multilayer structure of a metal region on which at least one silicide layer and a dielectric layer are alternately formed, a total number of the silicide layers and the dielectric layers being three layers to 12 layers, the multilayer structure having, in order on the metal region 1, a silicide layer B2, a dielectric layer M3, and a silicide layer M4 and the silicide layer B2 having a thickness of 5 nm to 25 nm, the dielectric layer M3 having a thickness of 10 nm to 45 nm, and the silicide layer M4 having a thickness of 2 nm to 15 nm.
