研究目的
To determine the optimum condition of the extracts of copigmenation which resulted in the optimum efficiency of DSSC solar cells by increasing the absorption ability of anthocyanin pigment photons.
研究成果
The highest efficiency of DSSC solar cells was achieved with a 1:2 concentration ratio of anthocyanin to salicylic acid and a 24-hour storage time, resulting in an efficiency of 1.32%. The copigmentation reaction enhanced the photon absorption ability of anthocyanin, leading to improved solar cell performance.
研究不足
The study focused on the use of anthocyanin from a specific fruit and its copigmentation with salicylic acid, which may limit the generalizability of the findings to other natural dyes or copigments.
1：Experimental Design and Method Selection:
The study used the method of copigmentation to form a more complex anthocyanin structure with a number of double bonds that can absorb more photons than the original anthocyanin.
2：Sample Selection and Data Sources:
Anthocyanin extract from fruits (Melastomamalabthricum L) was used as the sample.
3：List of Experimental Equipment and Materials:
Equipment included beakers, volumetric flasks, pipettes, magnetic stirers, spectrophotometers, and more. Materials included senduduk fruit, salicylic acid, hydrochloric acid, and others.
4：Experimental Procedures and Operational Workflow:
The process involved extraction of anthocyanin, copigmentation with salicylic acid, preparation of TiO2 thin film, and assembly of DSSC.
5：Data Analysis Methods:
Characterization was done using UV-Vis and FTIR spectrophotometers, and efficiency was calculated based on voltage and current measurements.
