用于热光伏器件的多层结构以及包括其的热光伏器件
摘要：
一种用于热光伏器件的多层结构(10)，该多层结构(10)包括热传递‑发射器单元(2)和光谱整形器(3)。所述热传递‑发射器单元(2)包括：腔室外壳(2.1)，其由耐高温材料制成，限定流通热传递室(2.2)；电磁辐射发射器(2.3)，其被配置为在暴露于高温时发射主要近红外辐射。所述光谱整形器(3)与所述电磁辐射发射器(2.3)相邻布置并且与所述电磁辐射发射器(2.3)热连接，其中，所述光谱整形器(3)被配置成针对最佳谱带的辐射的带通滤波器，并被配置成针对另外的非最佳谱带的辐射的反射器，使得随着辐射被朝着所述电磁辐射发射器(2.3)重新引导，所述第二非最佳谱带辐射被重复利用。
摘要（英）：

A multilayer structure (10) for thermophotovoltaic devices, comprising a heat transfer-emitter unit (2) and a spectral shaper (3). 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).
