Research ArticleOpen accessIn the abstractEFFECT OF AMBIENT AIR CONDITIONS ON LOW FREQUENCY NEGATIVE CAPACITANCE OF NC-TIO2/P3HT HETEROJUNCTION SOLAR CELLSH. Al-DmourWe report the negative capacitance of nanocrystalline titanium dioxide/poly (3-hexyl thiophene), nc-TiO2/P3HT, heterojunction solar cells. In air, low frequency negative capacitance has been observed under forward bias associated with high values of conductance. Interestingly, the negative capacitance disappear when the device was placed in vacuum chamber. These results are attributed to affect the ambient conditions on the charge carrier concentration … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 28 May 2014 · 6,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractTiO2 Nanoparticles-Coated Polypropylene Copolymer as Photocatalyst on Methylene Blue Photodegradation under Solar ExposureHasniah Aliah, Mahardika Prasetya Aji, Masturi et al.Problem statement: Pollutions of water bodies by dye wastes from textile industries and other sources have become critical consideration. A photocatalytic technique using semiconductor materials such as Titanium Dioxide (TiO2) activated by lights has been considered as one economical method to solve this problem. Approach: We attached titanium dioxide on the surface of polymer grains as photocatalyc agents using a … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 29 May 2012 · 7,859 accessesView PDFCite
