Evaluation of Annealing Effects on TiO₂ Nanorod Arrays for Dye-Sensitized Solar Cells by Equivalent Circuit Analysis

Article Preview

Abstract:

TiO₂ nanorod arrays (NRA) were synthesized via a facile hydrothermal method for preparing the dye-sensitized solar cells (DSSC). It was found that a post-thermal treatment facilitated enhancing the cell efficiency. The cells containing NRs underwent 500 °C annealing exhibited much higher efficiency than those un-sintered ones. Further, the internal resistance analysis was carried out to reveal the mechanism underlying the DSSC performance improvement. Specifically, the equivalent circuit model was employed to derivate the internal resistances, which was consistent with the experimental results. It was found that the sintered cells exhibited a higher series resistance and a lower shunt resistance than the un-sintered ones, suggesting the higher photocurrent density might result from the larger amount of dye loading.
