Size- tunable dual functional mesoporous TiO2 beads for high performance dye-sensitized solar cells |
| 초록 |
We successfully synthesizethemesoporous TiO2 beads, having controllable diameter in the rage from 120 to 750 nm, by solvothermal reaction with TTIP precursor and PVC-POEM graft copolymer at low temperature (at 100 oC). The prepared mesoporous TiO2 beads have the dual functions of high surface area because of the mesoporous structure and high light scattering effect because of the large size structure. The fabricated TiO2 film of photoelectrode is single titania layer composed of mesoporoussubmirometer-sized beads. Single layer reduce the fabrication process and interfacial resistance between the double layer (nanoparticle layer and scattering layer). As well as, the mesoporous TiO2 beads film showed a synergistic improvement on the charge collection efficiency resulting from the well interconnected mesopores and the strong scattering efficiency of the submirometer-sized beads, their effect improve the photoconversion efficiency. |
