- Abstract
- Here, we have studied the effect of water added electrolyte on the photovoltaic performance ofdye-sensitized solar cells (DSSCs). It was found that open-circuit voltage (Voc) increased and short-circuit currentdensity (jsc) decreased with the increase of the amount of added water in the electrolyte of the DSSCs. Electrochemicalimpedance spectroscopy (EIS) study showed that the electrolyte with added water shifted the dye loaded TiO2conduction band upward that eventually increased Voc of the cells. On the other hand, the upward shift of TiO2conduction band decreased the driving force for the electron injection from the lowest unoccupied molecular orbital(LUMO) of the dye molecules to the conduction band of TiO2 that resulted in decreased jsc.
