Abstract

Aiming at GaSb battery, this paper firstly explored the relationship between the emission spectrum of multilayer structure and material properties, aiming at the narrow and high spectral emissivity curve as possible. Based on this relationship, relevant materials were selected to optimize and improve the multilayer heat emitter in the thermal photovoltaic system. In this paper, Ge and SiO₂ is used as the material to make the thermal emitter have sharp and high thermal emission at 1.5μm. By using the approximation theory of crystal, the corresponding layer thickness of Ge and SiO₂ is 96nm and 125nm, respectively and its layer number is 4. Finally, the transfer matrix method is used to calculate the emission spectrum, and the above conclusions are verified.
