Controlled synthesis of anatase TiO2 nanofibers and its Dye sensitized solar cell properties |
| 초록 |
In the present investigation we have successfully synthesized anatase TiO2 nanofibers by electrospinning technique. The various feeding rate of electrospinning method was varied from 1.0 ml/h, 1.5 ml/h, 2.0 ml/h to 2.5 ml/h. The synthesized nanofibers were characterized by X-ray diffraction, scanning-and transmission electron microscopy, X-ray photoelectron spectroscopy. We found that, with increasing feed rate, nanofibers diameter and crystallanity increases. These nanofibers were further used for N-719 dye sensitized solar cells (DSSC). The 1.5 ml/h nanofiber based DSSC cell also exhibits promising 5.38 % enhanced conversion with a short short circuit current density (JSC) of 13.32 mA/cm2. The detailed interface and transient properties of these nanofiber based photoanodes in DSSCs were analyzed by electrochemical impedance spectroscopy (EIS) measurements, intensity modulated photocurrent/voltage spectroscopy (IMPS/IMVS) and open circuit voltage decay (OCVD). |
