Abstract
DSSCs based on quasi-solid type of electrolytes were prepared to investigate the influence of ionic mobility and recombination kinetics in electrolytes on DSSC performances. The improved ionic mobility of electrolyte in PMMA system resulted in the enhancement of J(sc) value in DSSC which was well confirmed with the incident photon-to-current spectra and the impedance analysis. Furthermore, the retarded recombination rate from TiO2 electrode to electrolyte in PMMA system enhanced the electron life time of DSSC in the photoanode. DSSCs based on quasi-solid type of electrolytes composed of PMMA showed a power conversion efficiency of 3.36% underAM 1.5 illumination (100mWcm(-2)) in an photo active area of 0.24 cm(-2), short circuit current density of 7.69mAcm(-2), open circuit photo voltage of 0.69 Vandafill-factor of 64%.
