| Abstract Scope |
The interface engineering is crucial in perovskite solar cells. Self-assembled monolayers (SAMs) are considered as an effective medium for interface regulation. The addition of SAMs can improve the surface morphology of perovskite layer, increase the crystallinity, reduce the defect density and charge recombination, and tune the work function to align the energy levels. In this study, a silane molecule is introduced to prepare the SAM in between the perovskite layer and indium tin oxide (ITO) to fill the potential gaps caused by large MeO-2PACz molecule in inverted perovskite solar cells. Benefitting from the silane SAM, the charge recombination at the hole-selective interface is suppressed and the power conversion efficiency reaches 18% which is improved by 12% compared to that without the silane SAM. Conductive atomic force microscope (C-AFM), Kelvin probe force microscope (KPFM), X-ray photoelectron spectroscopy (XPS), and scanning electron microscope(SEM) are used for characterizations. |
