Surface Passivation of Sputtered NiO _x Using a SAM Interface Layer to Enhance the Performance of Perovskite Solar Cells.

ABSTRACT: Sputtered NiO _x (sp-NiO _x ) is a preferred hole transporting material for perovskite solar cells because of its hole mobility, ease of manufacturability, good stability, and suitable Fermi level for hole extraction. However, uncontrolled defects in sp-NiO _x can limit the efficiency of solar cells fabricated with this hole transporting layer. An interfacial layer has been proposed to modify the sp-NiO _x /perovskite interface, which can contribute to improving the crystallinity of the perovskite film. Herein, a 2-(3,6-dimethoxy-9H-carbazol-9-yl)ethyl]phosphonic acid (MeO-2PACz) self-assembled monolayer was used to modify an sp-NiO _x surface. We found that the MeO-2PACz interlayer improves the qua
