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.
