| Outline of Final Research Achievements |
I revealed the key elements determining the electron transport properties in dye-sensitized solar cells by applying the control of exposed facet, nanoparticle morphology, and meso-porous construction with oriented anisotropic nano-sheets. I further applied these understandings to the control of electron transport, such as carrier injection, recombination, and transport in meso-porous TiO2 by controlling exposed facet to improve the conversion efficiency of dye-sensitized solar cells.
These researches were extensively applied to the peorvskite solar cells as the next-generation printable solar cells with high efficiency, which was not included in the proposal, in order to reveal the key elements of higher performances.
