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 optical spectroscopy 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 discover new semiconducting materials, unveil power loss mechanisms in devices, guide innovative device designs, and push device performance to the limits.
