研究目的
Investigating the use of Clitoria ternatea flowers as natural dyes in Dye-sensitized solar cells (DSSCs) to enhance photovoltaic performance.
研究成果
The study concluded that DSSCs fabricated with TiO2 and scattering layers using Clitoria ternatea flowers as natural dyes showed higher Power Conversion Efficiency (PCE) compared to those with TiO2 only. This improvement was attributed to the enhanced light path and better light management provided by the scattering layers.
研究不足
The study focused on the use of Clitoria ternatea flowers as natural dyes and their application in DSSCs with TiO2 semiconductors. The research did not explore other natural dyes or semiconductor materials extensively.
1：Experimental Design and Method Selection:
The study involved the preparation of natural dyes from Clitoria ternatea flowers and their application in DSSCs with two configurations of TiO2 semiconductors (TiO2 only and TiO2 with scattering layers).
2：Sample Selection and Data Sources:
Clitoria ternatea flowers were used as the source of natural dyes.
3：List of Experimental Equipment and Materials:
Equipment included a Food Grinder (FTC-Z100), UV-Vis Spectrophotometer (Jusco V-670), and a solar simulator (Bunko-Keiki Co. Ltd., Model Solar Simulator CEP-2000SRR). Materials included TiO2, Fluorine doped Tin Oxide (FTO) glass, and ethanol.
4：Experimental Procedures and Operational Workflow:
The flowers were dried, powdered, and immersed in ethanol to extract dyes. DSSCs were fabricated with TiO2 only and TiO2 with scattering layers, and their photovoltaic performance was measured.
5：Data Analysis Methods:
The photovoltaic performance was analyzed based on short-circuit current (Jsc), open circuit voltage (Voc), and Power Conversion Efficiency (PCE).
