Polymer gel electrolytes based on WO3 nanofillers are prepared for quasi solid state DSSC (QSDSSC). Two types of WO3 nanostructures (D-WO3, NP-WO3) are utilized as nanofillers of this polymer gel electrolytes, and the effects of the two nanofillers on the crystallinity of the electrolytes, charge transfer resistances at the electrode/electrolytes interface, and the performance of the quasi solid state DSSC are studied and compared. Compared with a conventional DSSC without WO3 nanofillers whose efficiency was 4.2 %, the energy conversion efficiency increased up to about 30 % and 44 % for the D-WO3 electrolyte based QSDSSC (5.46 %) and the NP-WO3 electrolyte based QSDSSC (6.05 %), respectively. |
