| Outline of Final Research Achievements |
In this research, we aimed to establish a method of extracting thermal radiation that exceeds the conventional power limit (blackbody limit) by using a system in which a high-temperature emitter and a photovoltaic cell are brought into close proximity via an intermediate substrate, and to establish the foundation for the development of high-power, high-efficiency thermophotovoltaic power generation systems. As a result, we have developed a systematic theory of near-field thermal radiation control and fabricated a near-field thermophotovoltaic device that integrated a high-temperature (up to 1200 K) thermal emitter and a room-temperature photovoltaic cell with a sub-wavelength gap (<140 nm). By using the developed device, we have succeeded for the first time in extracting near-field thermal radiation and photocurrent exceeding the blackbody limit in a single device.
