An Improvement of Photoanode Performance for Enhanced Efficiency in Dye-Sensitized Solar Cell

Abstract:

This works focus on an enhancement of dye-sensitized solar cell performance by improving photoanode which directly relates to shunt resistance and series resistance of the cell. Polyethylene glycol solution was prepared by dissolved polyethylene glycol in weight ratio of 10 and 30% in distilled water. ZnO past was prepared by mixing ZnO into polyethylene glycol solution, screened by doctor blade technique on fluorine doped tin oxide glass substrate and annealed at 450 °C for 1 h. The power conversion efficiency and fill factor were achieved as 0.81% and 0.44, respectively, because internal resistances were improved. The internal resistances were found that shunt resistance increased up to 4.35% and series resistance decreased down to 8.00% for 30% weight ratio of polyethylene glycol. These indicated that electron transfer in the cell was achieved in pathway direction.
