We modified the surface of the TiO2 photoelectrode using the aqueous metal nitrate solution, and investigated its effects on the performance of dye-sensitized solar cells (DSSCs). The DSSC with metal nitrate-modified photoelctrode showed an increase in the short circuit current (Jsc) and the open circuit voltage (Voc), resulting in a power conversion efficiency of 9.917%, compared to that (8.925%) of reference device with pristine TiO2. The suppression of charge recombination between photo-injected electrons and triiodide (I3-) ions in electrolytes was found to increase both Jsc and Voc of the device with the surface-modified photoelctrode. *Acknowledgements: This work is financially supported by the Ministry of Education, Science and Technology (MEST) through the fostering project of Industrial Complex Campus. |
