The current state of the art DSSCs are based on Pt counter electrodes which are very expensive. In addition to lower cost the carbon nanofibers have demonstrated lower charge transfer resistance and faster reaction rates as counter electrode for DSSCs. This innovation is expected to significantly decrease the cost of dye sensitized solar cells.
The current electrodes such as pure Pt or carbon nanoparticles for DSSCs are limited by high cost for Pt low conductivity and small surface area. The new developed composite electrodes can reduce cost increase conductivity and surface area with lower charge and transfer resistance and faster reaction rates as an electrode for DSSCs.
