Abstract
Indium-saving transparent conductive oxide (TCO) thin films, i.e., zinc and tin co-doped indium oxide (IZTO) films, were investigated for dye-sensitized solar cell (DSSC) applications. The films were prepared by the radio-frequency (RF) magnetron sputtering method utilizing a ceramic target with a nominal composition equal to In0.6Zn0.2Sn0.2O1.5. The substrate temperature was changed from room temperature to 400 degrees C while the RF power and the argon gas pressure during deposition were kept constant. The photovoltaic conversion efficiencies of the DSSC samples made with IZTO electrodes were compared with the samples made with FTO electrodes. Values of approximately 6.81% and 4.74% were obtained for the DSSC samples with FTO and IZTO electrodes, respectively, when the firing process was carried out in air atmosphere during DSSC fabrication. However, with the addition of post-annealing in argon or a forming gas, efficiency values increased to 6.06% or 5.54%, respectively, for the DSSC sample with an IZTO electrode.
