In this presentation, we will discuss the electronic and geometric structure at hybrid interfaces between a conducting oxide electrode or interlayer and an organic layer, such as those found in organic light-emitting diodes and solar cells. In particular, we will describe the mechanism by which organic layers modify the work function of the conducting oxide electrode [1] and we will pay special attention to the interfacial energy-level alignment. These parameters directly impact the charge-injection barrier [2].  [1] See, for instance, Y. Zhou, C. Fuentes-Hernandez, J. Shim, J. Meyer, A.J. Giordano, H. Li, P. Winget, T. Papadopoulos, H.
