| Outline of Final Research Achievements |
In order to make effective use of solar energy, the key technology of solar energy conversion is studied theoretically from the viewpoint of "carrier transport at the nano-interface". Specifically, organic thin film solar cells and water splitting photocatalysts are taken up as solar energy conversion technologies, and the control and optimization of nano-interface carrier transport required for each technology are studied based on theoretical and computational chemistry approach. The electronic factors on carrier recombination rates in organic thin film solar cells, carrier relaxation and carrier diffusion of water splitting photocatalysts are clarified.
