研究目的
Investigating the development of low-cost, environmental friendliness, outstanding catalytic activity, superior conductivity and good stability counter electrode (CE) catalyst in dye-sensitized solar cells (DSSCs) to promote the commercial application of DSSCs.
研究成果
The high-efficient WN/NrGO hybrids have a potential to replace the noble Pt for the low-cost DSSCs due to their excellent catalytic activity and charge transfer ability.
研究不足
The PCE of the WN/NrGO hybrids (7.42%) is slightly lower than that of the conventional Pt-based DSSCs (7.71%).
1：Experimental Design and Method Selection:
The WN/NrGO hybrids were synthesized by hydrothermal method followed by nitridation treatment under ammonia atmosphere.
2：Sample Selection and Data Sources:
The samples were characterized by XRD, Raman, XPS, SEM, and TEM measurements.
3：List of Experimental Equipment and Materials:
XRD, Raman spectrometer, XPS, SEM, TEM.
4：Experimental Procedures and Operational Workflow:
The WN/NrGO hybrids were prepared and then applied as the CE electrocatalyst for the I3? reduction in DSSCs.
5：Data Analysis Methods:
The photoelectric conversion performance was evaluated by J–V curves, CV measurements, Tafel curve, and EIS spectra.
