- Abstract
The new 3-D spongy NiCoS nanospheres have been successfully fabricated by a temperate hydrothermal method assisted sulfuration procedure and were used as counter electrode (CE) for dye-sensitized solar cells (DSSCs). The electrochemical tests such as cyclic voltammetry, electrochemical impedance spectra analysis, and Tafel curve measurements, indicated that the NiCoS nano-spheres electrode possesses high conductivity, low charge transfer resistance at the electrolyte-electrode interface, excellent electrocatalytic activity, and fast reaction kinetics for the I/I redox reaction for DSSCs. Furthermore, the DSSC fabricated using the NiCoS nanostructure CE exhibits an efficiency of 6.47% comparing the convention Pt with 6.33% as reference. The results indicated that the NiCoS nanostructure CE can display an excellent efficiency comparable to the Pt CE. Consequently, it is promising to substitute Pt CE for the NiCoS nanostructure in the future.
