Carbon molecular sieve (CMS) has been proposed as counter electrode (CE) catalyst in dye-sensitized solar cells (DSCs) for the first time. We evaluate the catalytic activities of CMS for the regeneration of different redox couples of I3−/I−, T2/T−, and Co3+/2+, and compare them with those of the traditional Pt CE, which is very expensive. For the I3−/I− redox couple, the CMS shows a relatively lower...
Pt/carbon fiber composite (Pt/Cf) with a low Pt loading of 1.0wt% is introduced into dye-sensitized solar cells as counter electrode (CE) catalyst. The cobalt-electrolyte based device using this composite CE achieves power conversion efficiency of 8.97%, a great improvement of 40.4% as compared to the Cf CE based device. This research provides a feasible route to reduce the dosage of Pt in DSCs system,...
