研究目的
Investigating the use of binary Cu-Co-S sulfide as an alternative to platinum counter electrode for the use in dye-sensitized solar cells.
研究成果
The CuxCoySz-3 sample demonstrated complete coverage of the FTO and showed better electrocatalytical activity in reducing triiodide species compared to Pt CE, leading to an 8.60% cell efficiency which is higher than the reference Pt-based cell at 7.75%.
研究不足
The study is limited to the solvothermal synthesis method and the specific binary metal sulfides used. The performance comparison is only against a Pt reference cell.
