Research Interests

We are concerned with describing the fundamental optical and electronic properties of organic and hybrid organic-inorganic semiconductor systems. We ultimately seek to exploit the unique properties of these materials to create novel electronic and optoelectronic devices. This interdisciplinary work involves elements of physics, chemistry, materials science and electrical engineering. Of particular focus is the improvement of organic and perovskite solar cells, organic light-emitting devices, and organic lasers.
