研究目的
To develop a semi-transparent, molybdenum disulphide (MoS2) flexible counter electrode (CE) for dye-sensitized solar cells (DSSCs) using electrodeposition method and to evaluate its performance compared to platinum-based CEs.
研究成果
The electrodeposited MoS2 CE demonstrated excellent catalytic properties and achieved a PCE of 4.84% in f-DSSCs, which is higher than normal PE-based f-DSSCs. The study highlights the potential of MoS2 as a cost-effective alternative to platinum CEs in DSSCs.
研究不足
The study focuses on the development and characterization of MoS2 CEs for f-DSSCs but does not extensively explore long-term stability under various environmental conditions or scalability for industrial production.
