Additive manufactuirng of active components: emitter, detectors, transistors and devices: sensors, displays, and solar cells by the printing of solution based inks is becoming a reality. Polymers, due to their synthetic and processing diversity play a critical role in ink formulaiton, as both binders and active material. Charge injection and transport at the interfaces between active layers and either contacts or gates critically determine the performance of thin film devices. In this talk, a series of morphological studies of the interfaces crucial to both transistors and organic photovoltaics will be presented. The role of contact and ink in determining interface composition and active layer structure will be discussed. Additionally, mechanisms for the use of contact modification layers to improve charge injection will be explored.
