The application of thin-film metamaterials as thermal emitters for thermophotovoltaic transforming heat to electricity is limited due to the low-melting metals. The synthesis of selective absorber/emitter metamaterials with high-melting refractory metals, nitrides as well as carbides for highest temperatures (> 1000°C) is the scientific challenge. The investigations are focused on thermal stability. The layer design of metamaterials such as length scales, materials, interlayers and microstructure will be adjusted and optimized for highest achievable working temperatures and required optical properties.

由于金属熔点低，薄膜超材料作为热光伏转换热电的热发射体的应用受到限制。在最高温度（> 1000°C）下用高熔点难熔金属、氮化物和碳化物合成选择性吸收体/发射体超材料是一项科学挑战。研究的重点是热稳定性。超材料的层设计（例如长度尺度、材料、夹层和微观结构）将进行调整和优化，以获得可实现的最高工作温度和所需的光学性能。
