Background: 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.
Description: Composite of carbon nanofibers with carbon nanoparticles and platinum nanoparticles can be introduced in DSCs, PECs, and fuel cells as new higher efficiency and lower cost electrodes. Such composites can introduce large surface area and hence exhibit more efficient electro-catalytic performance than traditional ones such as Pt. Large surface area and faster reaction rate than conventional electrodes can lead to reduced overall series resistance and thus improved performance.
Advantages: 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.
