The performance of organic solar cells strongly depends on the nanomorphology within the active organic semiconductor film. To be able to understand which morphology optimizes device performance on such small length scales a method that can quantify the molecular arrangement of organic molecules is needed. Grazing incidence wide angle x-ray scattering (GIWAXS) is a tool that allows the examination of ordered thin films on the nanoscale with high statistic relevance without damaging the sample. I will show different examples of measurements and analysis for small molecule and polymer systems.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
