Interfaces of solution processable doped organic transport layers with metals and conductive oxides — •Patrick Reiser1,2, Eric Mankel1,2, and Wolfram Jaegermann1,2 — 1Institute for Materials Science, Technische Universität Darmstadt — 2InnovationLab GmbH Heidelberg
Employing printing and solution processing of organic films has the potential to reduce manufacturing costs and to enable large scale flexible organic devices. A key to maintain high performance is given by proper interface engineering of printed layer towards the electrode material. Buffer layers or doped organic transport layers are used to create Ohmic contacts, which generally improves device performance. Here, we investigated the energetic and electrochemical properties of a doped hole transport material like P3HT and Spiro-OMeTAD towards electrodes like ITO or Silver by means of Photoelectron Spectroscopy. We further compare vacuum and solution processed films as well as the deposition sequence.
