Solid state dye-sensitized solar cells with organized mesoporous TiO2/ZnO interfacial layer templated by graft copolymer |
| 초록 |
An organized mesoporous TiO22/ZnO interfacial layer (om- TiO2/ZnO IF layer) with high porosity and good interconnectivity is prepared using an amphiphilic Poly(epichlorohydrin)-graft-poly(styrene) (PECH-g-PS) graft copolymer template. An improved performance of solid state dye-sensitized solar cells (ssDSSCs) is demonstrated by the introduction of om- TiO2/ZnO IF layer between nanocrystalline TiO2 and a fluorine-doped tin oxide substrate. The efficiency of the ssDSSCs using the om- TiO2/ZnO IF layer templated by PECH-g-PS with a solid state electrolyte reaches 5.0 %, which is higher than those of ssDSSCs using conventional TiO2 blocking layer (4.2 %). The improved efficiency is attributed to the antireflective property and good interconnectivity of the om- TiO2/ZnO IF layer, which results in improved light harvesting, decreased charge recombination, and reduced interfacial/internal resistance. |
