Research Description

I work on developing highly efficient solar cells and thermoelectric devices by controlling sunlight and heat in nanoscale using metamaterials. Our technology enables us to confine light and heat in a nanoscale, resulting in an unprecedented energy generation. This technique will be crucial for realizing eco-friendly society in the future.

Metamaterials used for controlling sun light and thermal control consist of metal nanostructures, whose shape, size, and material will determine their resonance wavelength. In other words, appropriate designing of metamaterial allows us to manipulate light and thermal absorption, reflection, and scattering properties of the metamaterial.The next step will be to apply this technique to developing optoelectronics devices, energy devices, and materials with useful applications.

About TUAT's tenure-track program

I thank the tenure-track program for providing me this prestigious post as a principle investigator. Although common in Europe and America, such tenure-track program is still relatively rare in Japan, especially considering the large number of young researchers and the limited number of faculty positions. The TUAT’s program provides me the precious opportunity to manage my own lab. It also enables me to easily seek advices from senior researchers in the university.

Future aspirations

Establishing new technologies that produce eco-friendly and clean energy is an urgent issue. I will pursue research with high impact that will bring about energy innovation. In future, we hope to return the results to our society to realize better human life.
