Modification of Working Electrode of Dye-Sensitized Solar Cell Using TiO₂ Nanopraticles/TiO₂ Nanofibers/CNT Composite

Abstract:

The working electrode of dye-sensitized solar cell was modified using composite material of TiO₂ particles/TiO₂ nanofibers/CNT by doctor blade method. Structural properties of pre-cursor materials and as-prepared working electrodes were well characterized by X-ray diffraction and scanning electron microscopy. The efficiency and relevant parameters of solar cells with modified electrodes were measured. The optimized weight ratios of 1 wt.% TiO₂ nanofibers derived from leucoxene and 0.01 wt.% CNT exhibited the highest improvement of DSSC efficiency with solar efficiency of 1.11% and fill factor of 0.32. The increase of current density may be originated from easier electron transfer that occurred in the device with modified TiO₂ particles/TiO₂ nanofibers/CNT composite.
