摘要

To address the limitations of liquid electrolytes in dye-sensitized solar cell (DSSC) fabrication, a recent study developed a gel polymer electrolyte (GPE) using polyvinyl alcohol (PVA), potassium iodide (KI), dimethyl sulfoxide (DMSO), ethylene carbonate (EC), propylene carbonate (PC) and diethyl carbonate (DEC). The preparation of GPEs using the solution mixing technique with the variation of the DEC concentration was then analyzed using electrical impedance spectroscopy (EIS) measurement to investigate the electrolyte's ionic conductivity, dielectric and transport properties. From the EIS results, the GP5 (12 wt.% of DEC) obtained a maximum conductivity of almost 17 × 10−3 S cm−1. XRD analysis shown that the GPEs has amorphous properties. Fourier-transform infrared (FTIR) spectroscopy was employed to investigate the complexation within the gel polymer electrolyte (GPE) system. The FTIR spectra of the PVA-EC-PC-KI-DEC GPE system reveal that the incorporation of DEC as an additive induces significant structural modifications in the polymer matrix. Notably, DEC enhances component interactions, reduces polymer crystallinity and facilitates ion mobility, collectively contributing to improved GPE performance. These findings underscore the pivotal role of DEC in optimizing the structural and functional properties of the GPE system. Thus, dye-sensitized solar cell (DSSC) utilizing GPEs containing DEC revealed a significant efficiency of 4.10%.
