| 中文摘要 | Polymer-inorganic hybrid solar cells with pure vertically aligned TiO2 nanorod arrays (TiO2-NRA) normally suffer from a rather low (<0.4 V) open-circuit voltage (V-oc). Recently, it has been demonstrated that the V-oc in polymer/TiO2-NRA solar cells can be improved to 0.7 V by formation of homostructured core-shell structures with single-crystalline TiO2 nanorod as core and the polycrystalline TiO2 quantum dots aggregation layer as shell. However, the V-oc was not achieved high enough, and effects of different crystallinity of shell on device performance have not been investigated. In this paper, we obtained three types of homostructured TiO2 core-shell nanoarrays with different crystallinity of TiO2 shell (amorphous, amorphous&crystalline, and polycrystalline) through controlling shell reaction time. The changes of device performance (in particular, the V-oc) in solar cells with these arrays are studied. Results show that the device V-oc gradually decreases when crystallinity of shell changes from amorphous to crystalline. Moreover, the reason for a larger V-oc by amorphous shell is analyzed. More dipoles could be produced at alpha-TiOx shell/polymer interface than crystalline TiO2 shell/polymer interface, which results in a further up-shifting conduction band edge in TiO2 nanorod core toward the local vacuum level of the polymer, along with a further enhanced V-oc.
