“…This is because the solubility of different dyes varies depending on the polarity of the extraction solvents, hence affecting directly the solubility and anchoring behavior of the extracted dyes onto TiO 2 , which then affect cell overall efficiency [29,30]. Polar aprotic solvents and polar protic solvents are two polar solvents commonly used to extract anthocyanins, and the polarity of these solvents can influence in terms of diffusion of dyes onto the TiO 2 surface, and hence, careful selection of solvent for extraction is important [31].…”

“…The performance of DSSC using dyes extracted in different solvents has been studied, and the reported results show that the performance does depend on the solvent properties such as polarity, acidity, dye combination, and temperature [21,31]. However, such studies focused on a few extraction solvents.…”

“…However, such studies focused on a few extraction solvents. For example, DSSC fabricated with curcumin dye in acetone, dimethylformamide, dimethyl sulfoxide, and ethanol yielded cell conversion efficiencies of 0.63, 0.44, 0.38, and 0.31 %, respectively [31]. Dyes extracted from Lawsonia inermis (henna) extracted in ethanol and a mixture of ethanol and water (4:1) showed conversion efficiencies of 0.66 and 0.52 %, respectively [25], whereas the dye extract of Melastoma fruit in deionized water and ethanol generated conversion efficiencies of 1.37 and 0.72 %, respectively [29].…”

We have tailored the extraction solvent of natural anthocyanin pigments from Ixora coccinea flower to lower charge transport resistance and enhance effective electron diffusion coefficient as well as absorption properties in DSSC sensitization. Six different extraction solvents were used in this study, namely, absolute ethanol, 70 % ethanol, acetone, dimethyl formamide, dimethyl sulfoxide, and distilled water. Dimethyl formamide was found to be able to extract the most anthocyanins from the Ixora flower, followed by dimethyl sulfoxide, acetone, absolute ethanol, 70 % ethanol, and distilled water, respectively. Dye-sensitized solar cells were fabricated using these extracted dyes as sensitizers and the cell performances were measured and characterized. The dye-sensitized solar cell equipped with a dye sensitizer extracted in 70 % ethanol achieved the highest conversion efficiency (ɳ=0.50±0.04 %) owing to its highest electron diffusion coefficient and lowest transport resistance in the TiO 2 /dye/electrolyte interface. This was followed by the cell equipped a with dye sensitizer extracted in acetone (ɳ=0.30±0.04 %), absolute ethanol (ɳ= 0.27±0.01 %), dimethyl formamide (ɳ=0.17±0.01 %), dimethyl sulfoxide (ɳ=0.16±0.01 %), and distilled water (ɳ= 0.09±0.003 %) in conversion efficiency performances, respectively. This study provides an insight into the importance of choosing the right medium for both dye extraction as well as the favorable solvent medium for dye adsorption onto TiO 2 .

Natural dye sensitized solar cells are a promising class of photovoltaic cells with the capacity of generating green energy at low production cost since no expensive equipment is required in their fabrication. Photovoltaics are a precious technology in the hasty world where energy prices are goes on increasing within seconds. Researchers are focusing to facilitate for producing eco-friendly, low cost and more efficient dye sensitized solar cells. In the present work we discuss the comparative photovoltaic studies of Lawsone, a natural dye from henna plant and Alizarin, a natural dye from the root of madder for fabricating the Dye sensitized solar cells (DSSCs). The absorption spectrum of Lawsone and Alizarin is found to be shifted to the longer wavelength region after the complex formation. As a result there is a significant increase in short circuit current density and conversion efficiency. This result is compared with the standard dye i.e. N719 dye.
