I will give a talk about the successful synthesis of well-organized mesoporous TiO2 films templated by the organized graft copolymer, i.e. PVC-g-POEM as a structure directing agent. Our group recently reported micron-thick, mesoporous TiO2 films templated by PVC-g-POEM, via the addition of the P25 nanoparticles. I will also introduce solid-state polymerizable conductive monomer with good conductivity and penetration to photoelectrode to I2-free solid-state DSSCs, which involves easily accessible and widely applicable fabrication method. Solid-state DSSC with 7.1 % efficiency was achieved via a graft copolymer-templated, organized mesoporous TiO2 film with a large surface area using spindle-shaped, preformed TiO2 nanoparticles and solid polymer electrolyte. High efficiency solid-state DSSCs were also developed using 3D organized films and nanopatterned TiO2 photoelectrodes. |
