研究目的
Investigating the effect of Ag-decorated TiO2 nanofibers on the efficiency of dye-sensitized solar cells.
研究成果
The Ag-decorated TiO2 nanofibers significantly improved the PCE of DSSCs by enhancing light absorption and reducing electron-hole recombination. The best efficiency achieved was 6.36%, representing an 18.0% increase over non-modified photoanodes.
研究不足
The study does not explore the long-term stability of the Ag-decorated TiO2 nanofibers in DSSCs or the scalability of the fabrication process.
1：Experimental Design and Method Selection:
The study involved the preparation of TiO2 NP/NF composite photoanodes by electrospinning, followed by Ag modification through soaking in AgNO3 solution and reduction under UV light.
2：Sample Selection and Data Sources:
The samples were characterized using XPS, SEM, TEM, and HRTEM to analyze their chemical composition and morphology.
3：List of Experimental Equipment and Materials:
Equipment included electrospinning setup, XPS, SEM, TEM, and HRTEM. Materials included titanium (IV) isopropoxide, polyvinyl pyrrolidone, acetic acid, ethanol, AgNO3, and ruthenium-based N719 dye.
4：Experimental Procedures and Operational Workflow:
The TiO2 NF films were prepared by electrospinning, calcined, and then modified with Ag. The DSSCs were assembled and their performance was evaluated.
5：Data Analysis Methods:
The performance of the DSSCs was analyzed through J-V curves and Nyquist plots.
