An improved supply of anthocyanin dye for creation of effective dye-sensitized solar cells grounded on natural dyes

Abstract In order to advance the power conversion efficiency of dye-sensitized solar cells, this article shows the selection of better sources of the sensitizer anthocyanin. The cells were created by combining liquid and solid electrolytes, adding natural dye, and employing a photo anode of aluminium-doped zinc oxide and a counter electrode of fluorine-doped tin oxide. Light harvesting efficiency, scanning electron microscopy, ultraviolet and infrared spectroscopy, and other methods were used to characterise the cells. From all the combinations made utilising different sources, the cell based on the D1 dye sample from Hibiscus sabdariffa L. (Manipur) had the best efficiency at 1.58 %. An effective DSSC was the end result of this strategy for identifying the optimal extraction source for anthocyanin natural dyes.
