OUR RESEARCH
Organic
Semiconductors
Organic
semiconductors are electronically conjugated molecules or polymers. The
electronic coupling in organic materials is in solids complex and depends
critically on their intermolecular arrangement. Our group has made significant
progress in understanding the molecular packing structure of semiconducting
polymers and the morphology of organic materials in thin films. These materials
are particularly interesting for energy conversion.
Organic
Thermoelectrics
We study the
thermoelectric effect in organic materials to determine if organic materials
can be used effectively to convert heat to electricity. Diffusion of charge
carriers in a thermal gradient in a thermoelectric material allows for
conversion of thermal to electrical energy (and by reciprocity the converse).
Our lab is working to understanding how to control electrical doping in organic
semiconductors and the fundamental processes that influence thermopower in
organic assemblies.
Organic
Photovoltaics
We are
working to understand the fundamental processes in charge generation and
extraction, to develop novel processing methods, and to understand the
degradation of organic photovoltaics (OPVs). Currently, organic photovoltaic
devices have efficiencies near 10% in cells, but relatively low efficiencies in
modules. Our approach is to develop well-characterized model systems that
reveal the underlying electronic processes in OPVs and enable rational study of
their behavior.
