Preparation of high porous TiO2 nanofibers by electorspinning and calcinations process for the dye sensitized solar cell(DSSC) |
| 초록 |
High porous TiO2 nanofibers were prepared by electrospinning to sol-gel process used precursors of titanium tetraisopropoxide (TTIP). (The surface morphology of nanofibers was examined by scanning electron microscopy (SEM) and Porosity of nanofibers was characterized using brunauer emmett teller (BET). Structure of the sintered composite was analyzed by themogravimetric analysis - differential scanning calorimetry (TGA-DSC). There are two endothermic peaks at 360℃ and 550℃, which indicate the degradation of polyvinyl pyrrolydone(PVP) and the formation of TiO2 respectively. In this study, found the average diameter of the resulting fibers in the 40~300nm range and manufactured fiber has porosity of 80%. |
