| Abstract: | A novel architecture of polytetrafluoroethylene (PTFE)-framed TiO2 electrodes is developed for dye-sensitized solar cells. The PTFE-framed TiO2 electrodes with various thicknesses have been successfully fabricated, ranging from 20 to 160 μm. The optimal energy conversion efficiency of 9.04% is achieved with a film thickness of 60 μm. The PTFE-framed structure not only provides tunable film thickness but a reliable and cost-effective way for the mass production of photo-electrodes. |
