Soft-Templated-Directed Fabrication of Functional Hybrid Materials with Tailored Structures for Application in Dye-Sensitized Solar Cells |
초록 |
We introduce unconventional routes for the enhancement of the efficiency of TiO2-based DSSCs by incorporation of tailored hybrid nanostructures prepared from self-assembled block copolymer nanotemplates. First, Massively-ordered arrays of TiO2 dots embedded in carbon matrix were fabricated via direct carbonization of UV-stabilized PS-b-P4VP block copolymer films containing TiO2 sol-gel precursors. DSSCs containing carbon/TiO2 thin layers exhibited remarkably enhanced power conversion efficiency compared with DSSCs based on neat TiO2 NPs. Second, we introduce a new class of organic/inorganic 1D photonic crystals exhibiting stop bands in the specific wavelength range, which was created by stepwise layer-by-layer deposition of UV-crosslinked BCP inverse micelle layers. The simple yet novel 1D layered BCP films have been introduced into the back-side of the counter electrodes as light reflector in DSSCs system to increase the light harvesting of dye. |
