Abstract

We present how the crystallinity of the electron transport layer can dramatically influence the transient characteristics of organic solar cells. We employed an inverted cell structure using TiO_x prepared by atomic layer deposition as an electron transport layer. The device possessing the amorphous phase TiO_x exhibited a continuous increase in the device characteristics upon continuous illumination at ambient, which is attributed to the filling of shallow electron traps within the amorphous phase TiO_x upon illumination. In contrast, the characteristics of the device with the crystalline phase TiO_x showed a negligible increase upon continuous illumination.
