Invitation to lectures by Elisabeth Leeb
The Organic Electronics and Photonics Research Group invites you to attend the lecture series Electrochemical Characterisation of Functional Materials: From Basic Principles to Organic Electronics, presented by Dr. Elisabeth Leeb from Johannes Kepler University Linz. The lectures will take place on 23 and 24 June at 10:00 a.m. in lecture hall P4.
Electrochemistry is now one of the key tools for studying functional materials, energy systems, and modern electronic devices. This lecture series will introduce the fundamental principles of electrochemistry and the experimental methods used to investigate charge transfer, redox processes, and material properties. It will then demonstrate how these techniques are applied in organic electronics research, including materials for solar cells, light-emitting devices, and organic transistors. The lectures will also present examples from current research on organic semiconductors and functional electronic interfaces.Abstract

Electrochemistry has become an indispensable tool across chemistry, materials science, and energy research, providing direct access to the thermodynamics, kinetics, and transport processes that govern functional materials and devices. From fundamental investigations of electron-transfer reactions to the characterisation of advanced optoelectronic materials, electrochemical methods offer unique insights into processes occurring at interfaces and within complex molecular systems.
In these lectures, I will first introduce the fundamental principles of electrochemistry and discuss how electrical measurements can be used to probe redox processes, reaction mechanisms, charge-transfer kinetics, and mass transport phenomena. Key techniques such as cyclic voltammetry, chronoamperometry, chronopotentiometry, and electrochemical impedance spectroscopy will be presented together with practical considerations for experimental design and data interpretation.
Building on these foundations, I will demonstrate how electrochemical methods can be applied to the field of organic electronics. Organic semiconductors used in solar cells, light-emitting devices, organic transistors, and related technologies rely on precisely controlled charge generation, transport, and storage processes. Electrochemical characterisation provides valuable information on frontier energy levels, charge-carrier formation, transport dynamics, and material stability, complementing optical and device-based measurements.
Using selected examples from contemporary research on conjugated molecules and polymers, organic photovoltaic materials, and functional electronic interfaces, I will highlight how electrochemical and spectroelectrochemical techniques can establish structure-property relationships and reveal the fundamental processes governing device performance. Together, these lectures will illustrate how electrochemistry serves both as a powerful analytical discipline and as an essential toolbox for the development and understanding of next-generation organic electronic materials.
