| titleOfInvention | A kind of preparation method of hollow prismatic quaternary nickel cobalt tungsten sulfide counter electrode catalyst |
| abstract | The invention discloses a preparation method of a hollow prismatic quaternary nickel-cobalt-tungsten sulfide counter-electrode catalyst. The catalyst provides a large number of active sites due to the synergistic effect of a variety of different metal ions and is doped with WS 2 . Therefore, it has better conductivity and stronger redox reaction, while the hollow structure provides more ion exchange channels, and its internal voids and porous properties are more conducive to the transport and exchange of electrolyte ions, resulting in better electrochemical performance. , applied to the counter electrode of dye-sensitized solar cells, the photoelectric conversion efficiency reached 9.41%, and it had good electrochemical stability in the I 3 − /I − electrolyte system. After 1000 continuous cyclic voltammetry scans After that, the photoelectric conversion efficiency can still maintain 88.9% of the initial value. |
