Abstract
Dye-sensitized photocathodes have the potential to significantly contribute to the efficiency of the solar light-To-current conversion in tandem dye-sensitized solar cells (DSSCs). A novel, highly porous nanoarchitecture of NiO is developed in this project. The spongelike material is grown by anodization, shows a virtually crack-free morphology, strongly adheres to the substrate, and can be grown with a controllable thickness of at least up to 6.5 μm. The oxide composition is NiO and the nanosponge exhibits p-Type semiconductive behavior. A doubling of the maximum reported p-Type DSSC efficiency compared to coumarin C343-sensitized NiO nanoparticle photocathodes can be achieved with the NiO nanosponge. The developed dye-sensitized p-Type NiO-based cathodes are promising for application as photocathodes in tandem DSSC devices.
