Structurecontrol of organized mesoporous TiO2 films templated by graft copolymers for dye-sensitized solar cells |
| 초록 |
Randomly microphase-separated graft copolymers have been self-reorganized so as to exhibit a micellar structure with excellent connectivity upon tuning the solvent affinity. These copolymers are used as a structure-directing agent for organized mesoporous TiO2 films with no grain boundaries, leading to enhanced solar conversion efficiency of dye-sensitized solar cells.The solar cell performance was maximized at 4.6% when the film thickness was increased to 2.5 mm. We believe that this graft copolymer-directed approach introducesa new and simple route toward the synthesis of well-organized metal oxide films as an alternative to a conventional block copolymer-based template.
