Electrical generation of Dye-Sensitized solar cells using sensitizer from rose flower

Link to publisher's homepage at http://www.ttp.net/Dye-sensitized solar cell (DSSC) is part of the thin film family that consists of a TiO2 electrode coating which acts as a photo electrode, sensitizer from dye molecules soaked in the TiO2 film, electrolyte layer and a counter electrode. This paper focuses on the usage of a sensitizer from the rose flower and will review some of the research conducted on dye sensitizers from other researcher. Rose flower also known as woody perennial of the genus Rosa, within the family Rosaceae is extracted and were used as sensitizer to fabricate dye sensitized solar cell (DSSC). The photoelectrochemical performance of Rose sensitized solar cell shows parameter of open circuit voltage, VOC, short circuit current, (ISC), fill factor (FF), solar cell efficiency (η), and peak absorbance rate as much as 0.13 V, 57.58 µA, 0.58, 0.85% and 3.5 at 550nm respectively. The photoelectrochemical performance of DSSC and the usage of natural sensitizer from Rose flower dye demonstrate good potential to be applied as a sensitizer yet detail investigations are essential in terms of its applicability for long term application

Potential of Purple Cabbage, Coffee, Blueberry and Turmeric as Nature Based Dyes for Dye Sensitized Solar Cell (DSSC)

AbstractNatural dyes extracted from purple cabbage, coffee, blueberry and turmeric were used as sensitizers to fabricate dye sensitized solar cells (DSSC). The dyes were extracted by using an ultrasonic extraction method by setting parameter of 30 oC at 30minutes and 37Hz. UV-Vis spectrophotometer is used to measure the absorbance of cocktail dyes which consist of purple cabbage and blueberry, turmeric and coffee that were extracted using ethanol and distilled water. From the result, the broadest spectrum between the extracted dyes is the cocktail dye from purple cabbage and blueberry which is in the range of 550nm and having the lowest photon energy of 1.85eV compare to the later. The result shows that, the combination of purple cabbage and blueberries as cocktail dye have good potential in future development of DSSC

Chlorophyll Pigments as Nature Based Dye for Dye-Sensitized Solar Cell (DSSC)

AbstractDye-sensitized solar cell (DSSC) was assembled using natural dyes from chlorophyll extracted from spinach as a sensitizer. In this work, the adsorption characteristic has been studied in harvesting sunlight using different solvents. The effect of solvents has been investigated by analyzing the absorption spectrum, bandgap and absorption coefficient of the dyes. From the UV-Vis absorption spectrum, it has been known that chlorophyll extracted with distilled water has the broader region of the visible light spectrum in the range of 400 to 720nm compared to chlorophyll extracted with ethanol. The lowest bandgap of dye also presented by extracted the chlorophyll with distilled water with 1.83eV and the absorption coefficient of 1.59 km-1. The photo electrochemical parameter for solar cell by using chlorophyll extracted with DI water solvent showed the open circuit voltage (Voc) of 440mV, current short circuit (Isc) of 0.35mA and a fill factor (FF) of 0.49
