To design a more efficient solar energy conversion system (light energy to electrical or chemical energy), it is important to reveal and understand the mechanisms of various chemical reactions at heterogeneous interfaces. We investigate the photochemical processes occurring on a variety of light energy conversion systems using advanced single-molecule, single-particle spectroscopy techniques and gain new insights related to spatial and temporal heterogeneities in reactions and structures, which are always masked by ensemble averaging.

Research Subjects
  • Single-molecule chemistry
  • Creation of efficient light conversion systems
