A new series of organic sulfide mediators with programmable redox properties is synthesized for efficient dye-sensitized solar cells (DSCs) through simple structural modification. Furthermore, addition of graphene components into the normal carbon counter electrode material can dramatically improve the catalytic activity of the counter electrode towards these sulfide mediators, giving the DSCs formed using these organic mediators good conversion efficiency.
