Popis: Polymer electrolytes based on hexanoyl chitosan/poly(vinyl chloride) (PVC) were prepared by employing sodium iodide (NaI) as the doping salt and 1-methyl-3-propylimidazolium iodide (MPImI) as the ionic liquid. The concentration of MPImI was varied from 2 to 10 wt.% while the amount of polymer and salt were kept constant. The effect of MPImI on the crystallinity, structural and conductivity properties of hexanoyl chitosan/PVC-NaI have been investigated. XRD results show that MPImI disrupts the crystallinity of polymer matrix while FTIR results show the existence of interactions among components in hexanoyl chitosan/PVC-NaI-MPImI. Polymer electrolyte without MPImI shows the highest conductivity of 1.5 × 10−5 S cm−1 at 303 K. Upon incorporation of MPImI, increment in conductivity can be observed. The hexanoyl chitosan/PVC-NaI-MPImI electrolytes were assembled into dye-sensitized solar cells (DSSCs) and the dependence of DSSCs performance on MPImI concentration has been investigated. DSSC with 8 wt.% of MPImI shows the energy conversion efficiency, η of 4.55 % with short circuit current density, Jsc of 10.34 mA cm-2 and open circuit voltage, Voc of 0.74 V.
