Research Interests

Dye-sensitized solar cells (DSSC) and Perovskite solar cells (PSC) are main research topics. Furthermore, quantum dots and organic semiconductor are also used to use as photo-electronic device material by print technique for photo-electronic device in my experience for trying to improve the performance of them, what is called printed electronics.
Focused on the research about well electron transfer excitation, charge separation and electron transfer in the devise for improving the power conversion efficiency (PCE), optimization of the device structure was important. Finally, we have reached good reproducibility over 10% PCE on DSSC.
Five years hence, we make effort to improve PCE on printed Perovskite solar cells. Photo-electronic conversion, Solar cells, Dye-sensitization, Perovskite, Printed electronics. This research is based on NEDO project.
