“…Natural pigments are derived from natural plants by grind, squeeze, filtration and purification [124], which result in its low cost and abundance. However, there is no relevant report about using natural pigment in FDSSCs, due to low performance in rigid DSSCs.…”

With growing demand for economic, eco-friendly, easy-manufacturing and renewable portable power source, flexible dye-sensitized solar cells (FDSSCs) exhibit a promising potential in the field of portable power sources. However, FDSSCs surfer from low conversion efficiency and poor stability, which hinder their applications. In this work, we have summarized recent development and challenges according to respective functions of their vital components (substrate, semiconductor film, sensitizer, electrolytes and counter electrode) as well as their effects on photoelectric conversion efficiency. Meanwhile, typical fabrication approaches have been analyzed for increasing the incident photon to current efficiency (IPCE). The approaches in rigid dye-sensitized solar cells (DSSCs) for improving performance are also introduced to provide the favorable direction for accelerating FDSSCs' application in field of potable power source.

“…Karakuş et al employed Pelargonium hortorum and Pelargonium grandiflorum as sensitizers in their DSSCs and achieved a PCE of 0.065% and 0.067%, respectively [32]. Ramanarayanan et al extracted the dye from the leaves of red amaranth and studied the effect of using different solvents, such as water and ethanol, and achieved PCE of 0.230% and 0.530%, respectively [33]. Hosseinnezhad et al extracted the dye from Sambucus ebulus and PCE of 1.15% was reported [34].…”

Here, three natural dyes were extracted from different fruits and leaves and used as sensitizers for dye-sensitized solar cells (DSSCs). Chlorophyll was extracted from spinach leaves using acetone as a solvent. Anthocyanin was extracted from red cabbage and onion peels using water. Different characterizations for the prepared natural dyes were conducted including UV-vis absorption, FTIR, and steady-state/time-resolved photoluminescence spectroscopy. Various DSSCs based on the extracted dyes were fabricated. The degradation in the power conversion efficiencies was monitored over a week. The effect of the TiO2 mesoporous layers on the efficiency was also studied. The interfaces between the natural dyes and the TiO2 layers were investigated using electrochemical impedance spectroscopy.
