Autor: Hatem Ghamri, Monzir S. Abdel-Latif, Taher M. El-Agez, Sofyan A. Taya, Amal Y. Batniji
Publikováno v: Journal of Theoretical and Applied Physics. 10:265-270
In this paper, the extract of Trigonella seeds was used as sensitizer for dye-sensitized solar cells (DSSCs). The natural dye was extracted from the seeds using water and alcohol as solvents for the raw material. The UV–Vis absorption spectra of Tr

Characterization of PVK Polymeric Material Using Rotating Polarizer and Analyzer Ellipsometer with a Speed Ratio 1:1
Autor: Taher M. El-Agez, Anas A. Alkanoo, Ahed Afghjani, Sofyan A. Taya
Publikováno v: Science, Technology and Development. 35:16-21
A homemade spectroscopic ellipsometer is designed indigenously to characterize Si-SiO2 sample and two Poly (9-vinylcarbazole) (PVK) films. In the constructed ellipsometer, the polarizer and analyzer rotate in the same direction with the same angular

Three Fresh Plant Seeds as Natural Dye Sensitizers for Titanium Dioxide Based Dye Sensitized Solar Cells
Autor: Sofyan A. Taya, Monzir S. Abdel-Latif, Taher M. El-Agez, Hatem S. El-Ghamri
Publikováno v: British Journal of Applied Science & Technology. 5:380-386
In this paper, we used the extracts of three fresh plant seeds as photosensitizers for DSSCs based on TiO 2 nanopowder as a semiconducting material. Ethanol was used to extract the dyes from the seeds. The fill factors of the cells sensitized with th

Dye-sensitized solar cells with natural dyes extracted from plant seeds
Autor: Amal Y. Batniji, Monzir S. Abdel-Latif, Sofyan A. Taya, Hatem S. El-Ghamri, Taher M. El-Agez
Publikováno v: Materials Science-Poland, Vol 32, Iss 4, Pp 547-554 (2014)
The application of natural dyes extracted from plant seeds in the fabrication of dye-sensitized solar cells (DSSCs) has been explored. Ten dyes were extracted from different plant seeds and used as sensitizers for DSSCs. The dyes were characterized u

Effect of the orientation of the fixed analyzer on the ellipsometric parameters in rotating polarizer and compensator ellipsometer with speed ratio 1:1
Autor: Taher M. El-Agez, Anas A. Alkanoo, Sofyan A. Taya
Publikováno v: Optical and Quantum Electronics. 47:2039-2053
In a recent work, rotating polarizer compensator ellipsometer (RPCE) with a fixed analyzer was proposed. Three different ellipsometric configurations were presented by considering different speed ratios of the rotating elements. It was shown the spee
