研究目的
Investigating the influence of 1-methyl-3-propylimidazolium iodide ionic liquid on the performance of dye-sensitized solar cell using hexanoyl chitosan/poly(vinyl chloride) based polymer electrolyte.
研究成果
Incorporation of MPImI increases the conductivity of hexanoyl chitosan/PVC-NaI by providing additional ions for conduction and increasing the amorphous phase of polymer. MPImI has enhanced the efficiency of the DSSC, with the highest efficiency of 4.55 % obtained with 8 wt.% MPImI. The efficiency enhancement is due to higher Jsc and lower recombination loss brought about by the MPImI.
研究不足
The study focuses on the effect of MPImI on the crystallinity and conductivity of hexanoyl chitosan/PVC-NaI electrolytes and their application in DSSCs. Potential areas for optimization include further investigation into the mechanisms of conductivity enhancement and recombination loss reduction.
1：Experimental Design and Method Selection:
Polymer electrolytes 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 amounts of polymer and salt were kept constant.
2：Sample Selection and Data Sources:
Hexanoyl chitosan/PVC-NaI electrolytes were prepared and characterized.
3：List of Experimental Equipment and Materials:
ATR-FTIR spectroscopic studies were carried out using a Thermo Fisher Scientific Nicolet iS10 spectrophotometer. X-ray diffraction (XRD) studies were carried out using an X-Pert PRO XRD. Conductivities were determined from the impedance measurements using a HIOKI 3532-50 LCR Hi-tester impedance spectrometer.
4：Experimental Procedures and Operational Workflow:
The preparation of hexanoyl chitosan/PVC-NaI electrolytes is similar to previous work. MPImI was added to the highest conducting sample. The concentration of MPImI was varied from 2 to 10 wt.% while the amounts of hexanoyl chitosan/PVC and NaI were kept constant.
5：Data Analysis Methods:
The obtained values of IC and IT were used to calculate the degree of crystallinity, XC according to Xc = IC/IT × 100%.
