Popis: Cu-doped NiS with PEDOT:PSS chrysanthemum flower-like structures, which were composed of many nanopetal bunches in a radial fashion, were synthesized using a modest, eco-friendly and cost effective method. The 5 wt.% Cuph/PEDOT:PSS produced a minute amount of PEDOT:PSS, which exhibiting outstanding electrochemical performance in QDSSCs. The synergetic effects of the composite were investigated and a PCE of 4.87%, fill factor of 0.51, Jsc of 13.75 mA cm−2, and Voc of 0.549 V in a polysulfide electrolyte were obtained. The electrode exhibited great electrocatalytic activities and lower charge transfer resistance than that of the bare NiS and Cu-doped NiS, making it a promising material for both fuel cells and QDSSCs. The improved performance of the 5 wt.% Cuph/PEDOT:PSS electrode was attributed mainly to the large surface area, greater electrical conductivity and high electrocatalytic activity.
