Functional Optoelectronic Nanomaterials
Prof. Dr. Gerasimos Konstantatos
- Activities:
We employ advances in nanoscience and we transform them into nanotechnology in solving real-world problems that current technology cannot address or do so at an affordable cost for the benefit of the society. We are doing so by assembling a group of physicists, chemists and engineers to tackle complex, interdisciplinary problems. We focus on novel functional nanomaterials, nanostructures and devices for optoelectronics and renewable energy applications.
Our main scope is on the development of low-cost, high-efficiency solar cells employing nanostructured materials of low toxicity and high abundance to address the TW challenge. We also exploit optical phenomena that emerge in the nanoscale to break long-standing trade-offs in solar cells and photodetectors. We study optoelectronically active plasmonic structures that may allow for ultra-thin low cost solar cells and ultra-sensitive photodetectors.
