Stacked graphene platelet nanofibers dispersed in the liquid electrolyte of highly efficient cobalt-mediator-based dye-sensitized solar cells†
Abstract
Stacked graphene platelet nanofibers (SGNF) dispersed in the electrolyte of dye-sensitized solar cells (DSSCs) can efficiently improve the charge transport and catalytic reactions of the Co(III)/(II) redox couple so that the quinoxaline dye AQ308-based DSSC containing 0.2 mg mL−1 SGNF exhibits the best power conversion efficiency (PCE) of 9.81%.
