I have broadly investigated the Pt/graphene/FTO counter electrode and i request to know what effect the Pt/graphene/FTO has on DSSC performance. This is owing to the fact that thePt and graphene has different work functions with Pt=6.1eV and Gr=4.6eV. i expect surface charges to enhance the catalytic activity of Pt? I am right?
Secondly the high specific area of graphene and its high conductivity contribute positively to the transfer of the reactants to the redox species..
thanks in advance
