Hydrothermal Synthesis of NiS2 Cubes with High Performance as Counter Electrodes in Dye-Sensitized Solar Cells
Electrocatalytic NiS 2 cubes were directly synthesized on F-doped tin oxide using a hydrothermal approach and used as counter electrode in dye-sensitized solar cells (DSSCs). The NiS 2 cubes displayed an excellent electrocatalytic activity in the reduction of I 3 − showing a power conversion efficiency of 5.56%, which is close to that of the Pt-containing DSSC (7.05%). Furthermore, the NiS 2 cubes showed a comparable stability to Pt. This is ascribed to the low resistance to diffusion and transfer of electrolyte ions. These results suggest that the NiS 2 cubes prepared through a facile process is a promising substitute to Pt electrode.
