Polymer-Based Counter Electrodes with Printable Materials 

PEDOT derivatives as cathode catalysts can also be immobilized by means of electrodeposition [30]. Poly(3,3-diethyl-3,4-dihydro-2H-thieno-[3,4-b][l,4]dioxepine) 

On the other hand, the film with a charge capacity of 40mCcm has the highest achve surface area, which is also about one order higher than that of platinum. 

This explains why the PPDOT-Et2 film prepared with a charge capacity of 40mCcm possesses similar catalytic ability to that of the platinum film. 

Fabrication of counter electrodes by simple coahng processes using PEDOT-based printable pastes as described here is an important key for DSSC manufacture with respect to minimum costs and rapid production. Design of semi-transparent counter electrodes also contributes to improved hght uhlization of the flexible ceU and modules.
