Vapor Coating Method Using Small-Molecule Organic Surface Modifiers to Replace N‑Type Metal Oxide Layers in Inverted Polymer Solar Cells Hyosung Choi Hak-Beom Kim Seo-Jin Ko Gi-Hwan Kim Jin Young Kim 10.1021/am500092a.s001 https://acs.figshare.com/articles/journal_contribution/Vapor_Coating_Method_Using_Small_Molecule_Organic_Surface_Modifiers_to_Replace_N_Type_Metal_Oxide_Layers_in_Inverted_Polymer_Solar_Cells/2293633 We investigate a simple fabrication method for vapor coating small-molecule organic interlayers as replacements for metal oxide films. The interfacial layers, which serve both as both surface modifiers to reduce the substrate work function and electron selective layers, maximize light absorption within the active layer while improving electron transport and compatibility between the active layer and cathode, leading to a ∼22% enhancement in power conversion efficiency and similar air stability compared to devices using a ZnO layer. 2014-05-14 00:00:00 surface modifiers power conversion efficiency substrate work function Vapor Coating Method light absorption ZnO layer air stability electron transport Inverted Polymer Solar CellsWe metal oxide films fabrication method
