- Abstract
- We investigate the effect of MnTiO3 surface treatment on the performance of dye-sensitized solar cells (DSSCs). The MnTiO3-treated TiO2 sample reveals a smoother surface with fewer cracks than the bare TiO2 sample. It is shown that the MnTiO3 is an amorphous layer (similar to 2 nm thick). The MnTiO3-treated TiO2 sample exhibits higher absorbance across the wavelength region of 450-800 nm than the bare TiO2 sample. The MnTiO3-treated sample gives the higher point of zero charge than the bare sample. Measurements show that the open-circuit voltage and the short circuit current are 0.64 and 0.67 V and 12.3 and 15.7 mA/cm(2) for DSSCs with the bare and MnTiO3-treated TiO2 electrodes, respectively. The MnTiO3 treatment improves the cell efficiency by about 25%. (C) 2013 Elsevier B.V. All rights reserved.
