제목 Characteristics of Perovskite solar cell with nano-structured MoO3 hole transfer layer prepared by hydrothermal synthesis
초록 In order to increase the hole mobility in Perovskite solar cell, a MoO3 nano-structured hole transfer layer was synthesised by hydrothermal synthesis. The structure of the device is FTO / CuO / MoO3 / CH3NH3PbI3 / P3HT / Ag. The CuO, MoO3, CH3NH3PbI3 and P3HT were used as a seed layer, a hole transfer layer(HTL), an active layer, and an electron transfer layer, respectively. The morphology of the MoO3 HTL was confirmed as like flower shape by SEM. The chemical bonding of the MoO3 nano-structured was measured by using XPS and Raman spectroscopy. As a result, MoO3 peak and Mo=O and O-Mo-O bonding were confirmed. The electrical characteristics of the device were measured using a solar simulator. The photoelectric conversion efficiency of 5.3% was obtained in the Perovskite solar cell with MoO3 nano-structured HTL.
