研究目的
Investigating the electro-catalytic activity of triiodide reduction in dye-sensitized solar cells (DSSCs) using multi-component X/W2C@X,N-C hybrid catalysts.
研究成果
The multi-component X/W2C@X,N-C hybrid catalysts exhibit enhanced electro-catalytic activity for triiodide reduction in DSSCs, with the electronegativity of dopants directly influencing the catalytic activity. The synergistic effect of different components in the catalyst promotes photovoltaic performance.
