Abstract EN
This paper is a part of natural dye solar cell project.
The dye extracted from blackberry fruit is successfully used in the fabrication of natural dye sensitized solar cells (NDSSC).
Blackberry dye extract is showed to contain anthocyanins which is an excellent light harvesting pigment needed for the generation of charge carriers for the production of electricity.
A strong absorbance in the green region (520 nm) is observed for blackberry dye at pH 1.
The color intensity of the blackberry dye is decreased with the gamma dose up to 5 kGy and then saturation started.
The high absorption range is found in blackberry dye 360-750 nm.
The absorption band edge value of the natural dye solutions of the blackberry is found 1.97 eV from the maximum peak position (at wavelength 630 nm).
Tauc gap (Eg) of the blackberry dye is found 1.96 eV for direct transition.
It is observed that the gamma dose up to 7 kGy showed no significant effect on both absorption edge and Tauc gap of blackberry dye.
The particles sizes range of the blackberry dye form the blackness pigment is found to 0.6-3.0 and 0.4-1.0 microns in diameter before and after gamma radiation.
The optimum conditions of NDSSC based on this study of Blackberry dye are found that VOC=0.5, JSC =0.7 mA.cm-1, FF=0.5, and η %=0.2.
