In the recent research we compared the solar energy performance of photogalvanic cell (PG cell) for two food dyes that act as photosensitizer tatrazine and sunset yellow in the DSS-EDTA (Dioctyl sodium sulphosuccinate - Ethylenediamine tetraacetic acid) system for power generation and its storage. Both are azo food dyes and act as photosensitizer, DSS acts as an anionic Surfactant and EDTA act as a reductant. The electrical parameters of both dye systems were studied and compared. The observed conversion efficiencies and fill factor for both systems in the DSS-EDTA system were 0.6163%, 0.2800, and 1.2186%, 0.2900, respectively. The stable photopotential (Voc) was 879 mV and 864.0 mV whereas the stable photocurrent (isc) was 220µA and 390 µA, respectively. In addition to having built-in storage capacity, the photogalvanic cell can operate in dark conditions. The amount of time required for the cell to reach half the value of power at power point, which was measure its performance called t1/2 of the cell. Cell performance of both PG cell was determined and for the Tartrazine - EDTA - DSS system it has been obtained 100 minutes while for the sunset yellow - EDTA - DSS system it was observed at 140 minutes. The current-voltage (i-v) characteristics of both the systems have been studied.

“…Therefore, the use of a very safe dye having high water solubility is urgently required for harvesting solar power through the solar cells like photo-galvanic cells. The Sunset Yellow FCF dye is a food dye having very high solubility in the water (19 gm/100 ml) and the reported conversion efficiency is 11.19 % and 2.59 %–4.17 % in photogalvanic cells [ 17 ], and DSSC [ 25 ] , respectively.…”

A series of new 5‐mono‐ and 5,5′‐bisamino‐substituted azothiazole derivatives was synthesized from the readily available diethyl azothiazole‐4,4′‐dicarboxylate. This reaction most likely comprises an initial Michael‐type addition by the respective primary alkyl and aromatic amines at the carbon atom C5 of the substrate. Subsequently, the resulting intermediates are readily oxidized by molecular oxygen to afford the amino‐substituted azothiazole derivatives. The latter exhibit remarkably red‐shifted absorption bands (λabs=507–661 nm) with high molar extinction coefficients and show a strong positive solvatochromism. As revealed by spectrometric titrations and circular and linear dichroism studies, the water‐soluble, bis‐(dimethylaminopropylamino)‐substituted azo dye associates with duplex DNA by formation of aggregates along the phosphate backbone at high ligand–DNA ratios (LDR) and by intercalation at low LDR, which also leads to a significant increase of the otherwise low emission intensity at 671 nm.
