摘要: This work is a pioneer attempt to fabricate quasi-solid dye-sensitized solar cell (QSDDSC) based on organosoluble starch derivative. Rheological characterizations of the PhSt-HEC blend gels exhibited viscoelastic properties favorable for electrolyte fabrication. From amplitude sweep and tack test analyses, it was evident that inclusion LiI improved rigidity property gels. On other hand, opposite true TPAI gels, which resulted in less rigid tacky electrolytes. The crystallinity found decline with increasing amount salt both systems. highest photoconversion efficiency 3.94% recorded upon addition 12.5 wt % this value one DSSC performance electrochemical impedance spectroscopy (EIS), deduced steric hindrance imposed by bulky cations aids hindering recombination between photoanode electrolyte.
