Research ArticleOpen accessIn the keywordsEFFECT 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 PDF Cite
