研究目的
To synthesize low-viscosity ionic liquids for application in dye-sensitized solar cells (DSSCs) to enhance the diffusion of redox couples and improve device performance.
研究成果
The synthesized ILs with unsaturated bonds exhibit lower viscosity and higher thermal stability, leading to improved DSSC performance. The best efficiency achieved was 6.85%, demonstrating the potential of low-viscosity ILs in enhancing DSSC efficiency.
研究不足
The study focuses on the synthesis and application of two specific ILs in DSSCs. Potential limitations include the scalability of the synthesis process and the generalizability of the findings to other types of ILs or solar cell configurations.
