Our group is focused on developing the new measurement science required to understand and control the chemical, physical and electrical properties of interfaces between electrical contacts and new electro-optical (active layer) materials, at nanometer length scales.  These materials encompass both organic active layers in organic solar cells (OPVs), hybrid perovskite active layers for new thin film solar cell technologies, and surface tethered semiconductor nanocrystals.  Such studies underpin the development of emerging energy conversion technologies (solar cells, photoactive nanocrystalline materials for light-to-fuel formation), and new active layers for light emisison, 

While reasonably efficient energy conversion and light emission platforms are becoming available, they are typyically expensive and not scalable.  The challenges in creating massively scalable energy conversion technologies, that are inexpensive and easily integrated into other technology platforms, often lies in undertanding and controling composition, structure and energetics of the interfaces between electrical contacts and active layers.
