Ouyang, Jianyong - National University of Singapore - Department of Materials Science and Engineering

个人简介

Dr. Jianyong Ouyang is an associate professor at the Department of Materials Science & Engineering, National University of Singapore. He received his PhD, master and bachelor degrees from the Institute for Molecular Science in Japan, the Institute of Chemistry of the Chinese Academy of Sciences and Department of Chemistry at Tsinghua University in China, respectively. He worked as a visiting scientist at the Institute for Molecular Science in Japan, an assistant professor at the Japanese Advanced Institute of Science and Technology, and a postdoctoral researcher at the University of California, Los Angeles before joining the National University of Singapore in 2006. He was a visiting scholar at Stanford University from Jan. 2018 to Nov. 2018. His lab at NUS continously renewed the world-record conductivity of PEDOT:PSS and the thermoelectric properties of polymers and ionic conductors. He is one of the main inventors of the nanoparticle/polymer memristors that can be the next-generation hardware of artificial intelligence. He also pioneered in charge ordering of charge-transfer organic salts

研究领域

1. Energy Materials and Devices I am interested to the energy conversion and energy storage. The energy conversion includes low-cost solar cells, such as polymer solar cells and dye-sensitized solar cells, and electrocatalysis. I am also interested to develop high-performance materials for energy storage. My lab achieved the highest photovoltaic efficiencies for dye-sensitized solar cells with carbon nanotubes and graphene as the counter electrode. 2. Nanometer Materials and Devices My interests on nanometer materials include the development, processing and application of functional nanometer materials, such as carbon nanotubes, graphene, polymer/nanoparticle memory devices, and antibacterial nanocoating. Recently, we developed methods to directly deposit nanostructured metals on substrates through the chemical reduction of metal precursors. 3. Organic Electronic Materials and Devices Organic electronic devices, including light-emitting diodes, photovoltaic cells, and field-effect transistors, have many important applications are regarded as the next-generation electronic devices due to their low fabrication cost and high mechanical flexibility. I am interested to the development of high-performance organic electronic materials and devices, including conducting polymers, conjugated polymers and organic molecules, photovoltaic cells and light-emitting diodes. We recently developed approaches to develop highly transparent and highly conductive polymer films. The polymer films have transparency and conductivity like indium tin oxide (ITO), the traditional transparent electrode material for optoelectronic devices.
