Thermal energy generation in space: Improved thermoelectric performance via metamaterial technology

Energy generation in Space poses a severe challenge, the answer to which may be the use of novel metamaterials for thermoelectric generators. Metamaterials can address this question by employing conventional materials and well-established fabrication technologies while leaving room for other approaches to increase the efficiency of thermoelectric generation. In the current study, we investigated possible configurations of metamaterials that could increase the efficiency of thermoelectric generators in Space.
