Nitrogen-doped graphene foams as metal-free counter electrodes in high-performance dye-sensitized solar cells.
Owing to their low-cost production, simple fabrication, and high energy conversion efficiency, dye-sensitized solar cells (DSSCs) have attracted much attention since Oregan and Gr tzel s seminal report in 1991. A typical DSSC device consists of a dye-adsorbed TiO2 photoanode, counter electrode, and iodide electrolyte. The counter (cathode) electrode plays a key role in regulating the DSSC devic...

متن کاملTransparent nickel selenide alloy counter electrodes for bifacial dye-sensitized solar cells exceeding 10% efficiency.
In the current work, we report a series of bifacial dye-sensitized solar cells (DSSCs) that provide power conversion efficiencies of more than 10% from bifacial irradiation. The device comprises an N719-sensitized TiO2 anode, a transparent nickel selenide (Ni-Se) alloy counter electrode (CE), and liquid electrolyte containing I(-)/I3(-) redox couples. Because of the high optical transparency, e...
متن کاملNitrogen-doped carbon nanotubes with metal nanoparticles as counter electrode materials for dye-sensitized solar cells.
Nitrogen-doped carbon nanotubes decorated with Co and Ni metal nanoparticles were assessed as counter electrodes (CEs) of dye-sensitized solar cells (DSSCs). These composites show good electrocatalytic activity toward the counter electrode reduction reaction (I3(-)→ I(-)) in DSSCs. The resulting devices using these composites as CEs display photovoltaic performance as good as, or even better th...
متن کاملRecent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells
Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes have shown significant properties such...
