- Abstract
- This work reports on the preparation of lithium acetate (LA)-incorporated TiO 2 electrodes by a very simple dip coating process and the effects of the modified electrode on the photovoltaic properties of dye-sensitized solar cells (DSSCs). The DSSC with a LA-modified TiO 2 layer exhibited an increase in both open circuit voltage and fill factor, resulting in a power conversion efficiency of 7.69% compared to that of a reference device with bare TiO 2 (6.82%). By monitoring the changes in electrochemical impedance spectra, dark current-voltage characteristics and incident photon-to-current conversion efficiency, it was revealed that the incorporated LA functioned as a surface dipole on the TiO 2 electrode. © 2012 Kyungil University.
