Welcome to StranksLab. Our research focuses on the optical and electronic properties of emerging semiconductors including metal halide perovskites, carbon allotropes and other organic semiconductors. We are particularly interested in low-cost, transformative electronics applications including photovoltaics and lighting. We use spectroscopy as a tool to understand material and device photophysics on a range of length and time scales, and relate these characteristics directly to local chemical, structural and morphological properties. This provides a unique platform to unveil loss mechanisms, discover new semiconducting materials, guide innovative device designs, push device performance to the limits and revise our understanding of semiconductor and defect behaviour.
