Probing the electrical conductivity of a film used in organic solar panels on a very small scale.
Taken using conductive atomic force microscopy at an image size of 5 microns with a +2V bias applied to the substrate. Thin film cast from a solution of a small molecule donor and acceptor mixed in chlorobenzene onto a glass/ITO/PEDOT:PSS surface.
