研究领域

Solution-processing holds promise for low-cost fabrication of large-area optoelectronic devices, such as light-emitting diodes (LEDs) and solar cells. It is of critical importance to achieve performance levels of solution-processed devices comparable to those of state-of-the-art devices produced by vacuum deposition. To meet this goal, our interdisciplinary research program spans materials chemistry, device engineering and device physics. We also collaborate actively with a number of other groups. Materials Chemistry Materials chemistry allows creation of solution-processable materials with tailored electronic properties. The realization of new materials can enable revolutionary design of device structure and significant improvement of device performance. The research in our group involves (but not limited to) design and synthesis of oxide interfacial layers, surface modification of the interfacial layers and design and deposition of high-quality organic-inorganic perovskite films. Device Engineering Device engineering refers to the processing and integration of all the building blocks, including the active layers, the charge-transporting layers and the electrodes in a rational manner, leading to working devices. Often subtle changes in the device structure or materials processing can result in very different behaviors of devices. We are now focusing on quantum-dot LEDs and hybrid perovskite based LEDs and solar cells. Device Physics Physicists and spectroscopists developed many exquisite tools to understand in-depth the physical processes that govern the performance of optoelectronic devices. Some of these techniques can be performed on operational devices. We are applying these tools to our solution-processed devices. We are particularly interested in the interfacial processes, such as charge injection and interfacial recombination. The knowledge will help us in designing advanced functional materials and new device architecture.
