Beschreibung
Zusammenfassung:	A multilayer structure (10) for thermophotovoltaic devices, comprising a heat transfer-emitter unit (2) and a spectral shaper (3)is disclosed. The heat transfer-emitter unit (2) comprising a chamber enclosure (2.1) made of a high temperature resistant material, defining a flow-through heat transfer chamber (2.2); an electro-magnetic radiation emitter (2.3) configured for emitting predominantly near-infrared radiation when exposed to high temperatures. The spectral shaper (3) is arranged adjacent to and thermally connected with said electro-magnetic radiation emitter (2.3), wherein the spectral shaper (3) is configured as a band pass filter for an optimal spectral band of the radiation and as a reflector for further, non-optimal spectral band(s) of the radiation, so that said second, non-optimal spectral band radiation is recycled as radiation redirected towards the electro-magnetic radiation emitter (2.3).
