Prerequisites photogalvanic cells that the dyes should be lowcost, easily available for schools and known to students from their everyday lives.

More chemistry-related photogalvanic cells for suitable sensitizers are: Finally there should be no safety hazards. Especially saffron proved to work as a suitable dye for the use as alternative sensitizer for titania.

Efficiency of light-energy conversion in photogalvanic cells and water cleavage

The dye that is mainly responsible photogalvanic cells the yellow color of saffron is crocin Figure 4. Crocin is a carotene derivative with disaccharide substituents, which cause the dye to be water-soluble.


The following photogalvanic cells focus on experiments with saffron and the pure substance crocin. The experimental section presents a sequence of lab experiments useful for investigations on the dyes with respect to the preparations of the solutions, the properties, stability and, finally, the use as sensitizer in photogalvanic cells.

And a metal based photo galvanic solar panel is the most commonly photogalvanic cells solar technology to generate electrical energy was studied [6].

Use of some reductant and photo sensitizer in photo galvanic cells for solar energy conversion and storage was investigated [7].

The studies of photo galvanic cell photogalvanic cells various dyes with reductant and surfactant were done [8] [9]. Recently the photo galvanic effect in various interesting system were observed [10] [11]. The photo chemical conversion of solar energy into electrical energy was studied [12] [13].

A detailed literature [14] - [20] survey reveals that different photosensitize photogalvanic cells EDTA have been used in photo galvanic cells, but no attention has been paid tousle of the NaLS-orange G system in the photo galvanic cell for solar energy conversion and storage.

All the Solutions were prepared in doubly distilled water and kept in amber colored containers to protect them from sunlight. A platinum electrode 1. A water filter was used photogalvanic cells cut off infrared radiations.

The photochemical bleaching of orange G was studied potentiometrically. A digital pH meter modal?


III and a microameter were used to measure the potential and current generated by the system, respectively. The experimental set-up photogalvanic cells photogalvanic cell is given in Figure 1.
