Anthocyanin components for dye-sensitized solar cells extracted from Teclea Shimperi fruit as light-harvesting materials
In this work, anthocyanin components extracted from Teclea Shimperi fruit has been utilized as a light harvester for dye-sensitized solar cells (DSSCs). The anthocyanin dyes were anchored on the TiO2 surface and used as a light harvester, while the quasi-solid state electrolyte (I−/I3−) was sandwiched in between the PEDOT coated FTO counter electrode and photoelectrode. The assembled photoanode, PEDOT coated FTO counter electrode, and quasi-solid state electrolyte were illuminated by a light intensity of 100 mW cm−2 to measure the photoelectrochemical parameters. Under this illumination, the best power conversion efficiency of 0.340 ± 0.012% (η) was achieved. The as-prepared DSSC was also showed a Jsc = 1.240 ± 0.021 mA cm−2, Voc = 0.453 ± 0.009 V, and a FF of 60.367 ± 0.617% using acidified ethanol for extraction. The maximum value of IPCE (~5%) was recorded at 630 nm from a cell made by anthocyanin extracted using acidified ethanol. This is the first report that unveiled the possibility of extracting heterocyclic compounds of anthocyanin type from Teclea Shimperi fruit using different solvents. Thus, the use of Teclea Shimperi fruit as natural sensitizers can be an indispensable option to produce low-cost and environmentally friendly DSSCs.
