Abstract
ABSTRACTThe impedance of well-characterized KI-incorporated glucosyl carboxonium ion-based biopolymer crust electrolytes up to a maximum 2.7 wt% was measured using electrical impedance spectroscopy. Enhanced ionic conductivity of 2.3657 × 10−2 S cm−1 on the addition of 2.7 wt% of KI was observed in contrast to earlier reported value for pure GCI of 4.5278 × 10−4 S cm−1. This is attributed due to the increased concentration of KI in the system and is corroborated with increased ion density (n), mobility (µ), and diffusion coefficients (D). Dielectric and modulus study shows the capacitive nature of electrolyte. Fabricated dye-sensitized solar cell using pure glucosyl carboxonium ion crust and KI-incorporated glucosyl carboxonium ion crust shows the efficiency of 1.19% for pure and shows the efficiency of 2.14% for 2.6 wt% of KI in glucosyl carboxonium ion at 1 sun condition.
