Abstract :
We have demonstrated a modified doctor-blade method using a dense TiO2 paste in combination with moderate compression for preparation of TiO2 thin film. Dye-sensitized solar cell (DSSC) with the working area of 0.25 cm2 using that novel TiO2 thin film was observed to show its superior photovoltaic performance at AM 1.5: VOC of 0.77 V, JSC of 18.2 mA/cm2, FF of 0.50 and ¿ of 7.0 %. This overall conversion efficiency was approximately 2 times as much as that of a corresponding DSSC fabricated with a conventional TiO2 thin film (¿ of 3.7%). The modified doctor-blade method was also found to significantly improve the efficiencies of DSSCs with the working areas of 0.5, 1.0 and 5.0 cm2.
