| DSSCs were fabricated with the structure of FTO/TiO2-ZnPc-dye/electrolyte/Pt/FTO. The electrolytes containing (PVP-co-VAc)/PMMA and a mixture of KI and TPAI salts were prepared by solution cast method. The cell fabricated with an electrolyte containing 30 wt% TPAI exhibited a higher efficiency of 1.32%. However, the cell with an electrolyte including 25 wt% TPAI/5 wt% KI exhibited the best power conversion efficiency of 1.1% under 1000 W/m2 light intensity. Field emission scanning electron microscopy images show that the TiO2 nanoparticles were comparatively well dispersed but are irregularly shaped due to agglomeration. |
