研究目的
To address the inherent rigid structure and superior absorption properties of the working electrode in dye-sensitized solar cells (DSSCs) by fabricating flexible composite sheets of titanium dioxide (TiO2) incorporated with natural lignocelluloses fibers.
研究成果
The incorporation of LC fibers in TiO2 enhanced the porosity of the samples to adsorb more dye for superior energy conversion characteristics. The fabricated TiO2/LC composite sheet showed a high efficiency of 2.95%, making it suitable for modern bendable DSSC applications.
研究不足
The study does not discuss the long-term stability and durability of the fabricated DSSCs under various environmental conditions.
1：Experimental Design and Method Selection:
The study involved the fabrication of flexible composite sheets of TiO2 by incorporating natural lignocelluloses fibers extracted from Typha Angustifolia. The composites were characterized using SEM, FTIR, and UV-VIS spectroscopy.
2：Sample Selection and Data Sources:
Natural dye was extracted from fresh flowers (Raspberry), and lignocelluloses fibers were extracted from the stem of self-growing plants, Monochoria Vaginails and Typha Angustifolia.
3：List of Experimental Equipment and Materials:
ZnO and TiO2 powder, FTO glass, surlyn 1702, acetone, propanol, methanol, ethanol, lithium iodide, potassium iodide, and Iodine were used.
4：Experimental Procedures and Operational Workflow:
The fabrication process included the preparation of TiO2 and lignocelluloses fibers composite, dye and electrolyte, working and counter electrodes, and cell assembly.
5：Data Analysis Methods:
The performance of the DSSCs was analyzed using J-V measurements.
