D2 - Lateral and vertical charge-transport study in templated molecular layers


Principle Investigator: Prof. Klaus Meerholz

This project will focus on studying various Molecular Building Blocks suitable for use in Organic Solar Cells, e.g. merocyanines and squaraines. Our goal is to establish structure / morphology / device performance correlations to gain understanding of the charge transport as a function of molecular packing and order. We strive to tune the order by using different templates and molecular building blocks with varying intermolecular interactions.

This project will be a joint collaboration with Dr. Dirk Hertel.
