| Outline of Final Research Achievements |
In this study, we conducted fundamental research on solar thermophotovoltaic (Solar-TPV) power generation. Key technologies in this study are solar-selective absorbers and wavelength-selective emitters. Therefore, we focused on metamaterials that can flexibly control radiative properties. We designed the metamaterial structure based on theory and numerical analysis and succeeded in obtaining performance almost as designed as Solar-TPV emitter. We also showed that the photovoltaic power generation is possible in the experiment in the vacuum. We also proposed a metamaterial using a core-shell type nanoparticle array and fishnet type for solar-selective absorbers. In addition, we have also studied large-area wavelength- selective emitter in the infrared region.
