Abstract

Article history: Polyaniline-grafted silica nanocomposites (PANI-SiO ), which are synthesized through in-situ surface Received 2 June 2017 chemical oxidative polymerization of aniline with the NH -modified silica nanoparticles, are exploited Received in revised form 21 July 2017 as gelators in the ionic-liquid electrolytes for dye-sensitized solar cells (DSCs). It can be clearly seen Accepted 2 August 2017 that the PANI-SiO nanocomposites have the well-interconnected network structure, which not only Available online 5 August 2017 serve as gelators to effectively solidfy the ionic-liquid electrolytes, but also significantly improve the ion conductivity of electrolytes and the diffusion coefficient of I ions. As a result, an optimal efficiency of Keywords: 7.15% for DSC using gel electrolyte is achieved due to the enhancement of photocurrent density (J ) and sc Polyaniline fill factor (FF), which is increased by 18.99% than that of the cell using ionic-liquid electrolyte.
