Numerous metal complexes and organic dyes have been used and utilized as sensitizers [ 3 ]. Although such results provide better efficiency and high durability, the advantages are often offset by their high cost of production, complicated synthetic routes, environmental impact, and the tendency to undergo degradation in presence of water [ 6 ]. In contrast, the natural organic dyes are widely available and involve simple preparation, nontoxic, and complete biodegradation [ 7 ].
The use of nontoxic natural pigments as sensitizer would definitely enhance the environmental and economic benefits of this alternative form of solar energy conversion [ 8 ]. Due to these reasons, natural dyes are becoming attractive inexpensive candidates for renewable energy resources.

The natural dye sensitizer may still produce very low efficiency, but with continuous advanced studies and research, improvisation of the efficiency of DSSCs has become a reality and hopeful. Anthocyanins are the most abundant, naturally occurring flavonoid pigments which often give a bright red, blue, or violet color to plant petals, fruits, and stems [ 9 ]. Sometimes, they are present in a range of tissues including roots, tubers, and stems [ 4 ].
Since anthocyanin shows the red to blue color of the visible spectrum, it is considered as one of the best sensitizers for wide bandgap semiconductors [ 3 ]. The performance of the cell mainly depends on the dye used as sensitizer [ 10 ]. Optimizing the structure of a natural dye is necessary to improve DSSC efficiency [ 4 ].
Although anthocyanin pigments are abundant in plants, isolated anthocyanin pigments are highly instable and degradable [ 11 ]. Their stability is affected by several factors including pH, storage temperature, and sunlight exposure levels [ 12 ].
Hence, it is important to evaluate the optimum conditions required to maintain the anthocyanin stability over a long period of time.
Storage temperature plays a critical role for anthocyanin stability [ 13 ]. Investigating the effects of storage temperature on anthocyanin degradation will be highly beneficial because one of the vital steps in the procedure of manufacturing DSSCs involves storage of the extracted pigments.
