dc.description.abstract | Preparation of low-cost electrocatalytic counter electrode (CE) at low temperature is desired in the fabrication of photo-electrochemical quasi-solid state dye-sensitized solar cell (Qs-DSSC). We present facile doping of fumed silica (SiO2) as mesoporous nano-spacers in cationically functionalized graphite network and its synthesis into an electrically conductive hybrid paste for Qs-DSSC CEs. Polyethylene oxide (3%) based electrolyte solution is used as a quasi-solid gel electrolyte. With an optimized quantity of fumed silica nano-spacers (10%), an increase of 53.6% is achieved in power conversion efficiency (PCE) compared to bare cationised graphite coated CE. Our suggested Si@G 10% CE demonstrates commendable power conversion efficiency of 6.42% compared to 7.32% with expensive platinum (Pt) based Qs-DSSC. It exhibits a low charge transfer resistance (R-CT) of 0.61 Omega cm(2), owing to the improved interconnection, formation of the porous structure, and enhanced mobility of electrolyte ions. The cyclic voltammetry (CV) shows excellent electro-catalytic activity towards the I-/I-3(-) redox couple and it is stable up to 50 cycles at a scan rate of 10 mV s(-1). The facile synthesis route, excellent electro-catalytic activity, appreciable stability, and considerable photovoltaic performance makes Si@G 10% based CE a promising candidate for Qs-DSSC fabrication.
