Biographical Information

  Dr. Liyuan Han is a director of photovoltaic materials unit, National Institute for Materials Science. He received a doctor’s degree from the University of Osaka Prefecture in 1988. During 1990-1993, he worked in Dainippon Ink & Chemicals Inc. on organic photoconductor materials. He then moved to SHARP Corporation. He has been investigating dye-sensitized solar cells, especially, improving the conversion efficiency of cells and sub-modules, and developing new sensitized dyes, since 1996. He moved to current position from June 2008. His major researches include proposing the equivalent circuit model of DSCs and applying the back-contact model into dye-sensitized solar cells.   He is inventor in about 100 patents and author in ca 80 scientific publications in the field of dye sensitized solar cells. His current research interests involve foundational research dye-sensitized solar cells, organic solar cells and quantum dot solar cells.

Research Interests

  Dye-sensitized solar cells, organic solar cells and quantum dot solar cells.
