摘要：
The band alignments at the interface of ZnO/HC(NH2)(2)PbI3 (FAPbI(3)) heterojunction were measured by X-ray photoelectron spectroscopy. Core levels of Pb 5d and Zn 3d were utilized to align the valence-band offset (VBO). The VBO was determined to be 1.86 +/- 0.30 eV, and the conduction-band offset (CBO) was concluded to be 0.05 +/- 0.30 eV, manifesting that the ZnO/FAPbI3 heterojunction has a type-I band alignment. The data of the band alignment of ZnO/FAPbI(3) heterojunction may benefit the design and development of novel perovskite solar cells (PSCs). (C) 2015 Elsevier B.V. All rights reserved.
