Dye-sensitized solar cell (DSSC) has attracted immense interest over the past decade due to its low cost and simplicity as a renewable energy source. In DSSC, the photo-anode that governs the collection and transportation of photo-excited electrons plays a critical role in determining the cell performance. In particular, the thickness of the photo-anode is known to be one of the decisive factors in dictating cell efficiency. In this paper, the thickness effect of TiO2 film as photo-anode on the photovoltaic performance of DSSC is studied. The TiO2 films were characterized by UV-visible absorbance spectroscopy to correlate the film thickness with the light harvesting efficiency of DSSC. The effects of film thickness on the photocurrent density-voltage characteristics of DSSCs were also investigated. The optimized thickness (4m) of the TiO2 film was discovered to be the best compromise between the amount of dye loading and the electron transport resistance.
