摘要

We report the negative capacitance of nanocrystalline titanium dioxide/poly (3-hexyl thiophene), nc-TiO_2/P3HT, heterojunction solar cells. In air, a low frequency negative capacitance has been observed under forward bias condition associated with high values of conductance. Interestingly, the negative capacitance disappear when the device is placed in vacuum chamber. These results are attributed to affect the ambient condition on the charge carrier concentration in materials used to fabricated solar cells and increase bulk region resistance.
