Our research on organic photonics and iontronics straddles the boundaries of condensed matter physics, device physics, photo-physics, and solid polymer electrolytes. We use direct imaging and optical probing to explore the emerging sciences of mixed organic semiconductors in which electrons, ions and photons interact in many unexpected ways. Our multi-disciplinary research has potential applications in renewable energy, solid state lighting and energy storage.
